What is project? What is project cont’d? Project is a temporary endeavor undertaken to create a unique product or service. Temporary means that every project has a definite end. Unique means that the product or service is different in some distinguishing way from all similar products or services. A project has a unique purpose. Every project should have a well-defined objective. What is project cont’d project is an endeavor in which human, (or machine),material and financial resources are organized in a novel way, to undertake a unique scope of work, of given specification, within constraints of cost and time, so as to deliver beneficial change defined by quantitative and qualitative objectives. What is project cont’d A project is a plan or proposal consisting of a sequence of unique, complex, and connected activities having one goal or purpose and that must be completed by a specific time, within budget, and according to specification. Sequence of activities: A project comprises a number of activities that must be completed in some specified order, or sequence. What is project cont’d Unique activities: The activities in a project must be unique. A project has never happened before, and it will never happen again under the same conditions. Complex activities: The activities that make up the project are not simple, repetitive acts Connected Activities: Connectedness implies that there is a logical or technical relationship between pairs of activities. One goal: Projects must have a single goal. What is project cont’d Specified Time: Projects have a specified completion date. This date can be self-imposed by management or externally specified by a customer or government h agency. Within Budget: Projects also have resource limits, such as a limited amount of people, money, or machines that are dedicated to the project. According to Specification: The customer, or the recipient of the project's deliverables, expects a certain level of functionality and quality from the project What is project cont’d Some attributes: A project requires resources. Resources include people, hardware, software, or other assets. A project should have a primary sponsor or customer. A project involves uncertainty It is an answer to a business opportunity or problem It goes through distinct stages -It has a beginning, a middle and an end… What is project cont’d It must be approved to proceed -It consumes resources... It is confined by definable boundaries -It has defined scope, budget, schedule, quality... Scope: What is and is not included as part of the project Budget : How much can be expended for direct and indirect costs Schedule : Start and end dates for each deliverable Quality : Qualitative terms, conditions and expectations expressing each stakeholders’ interests What is project cont’d Every project is constrained in different ways by its scope, time goals, and cost goals. Scope: What is the project trying to accomplish? Time: How long should it take to complete the project? Cost: What should it cost to complete the project? These limitations are referred to us the Triple Constraint of project management. Managing the triple constraint means making trade-offs between project scope, time and cost goals for a project. 2. Operations and Projects Is project the same with operations? PROJECTS vs. OPERATIONS Projects differ from ongoing operations in the following ways: projects start and end projects are focused on one objective projects have short term strategies projects end!! ongoing operations are focused on continuing support of an organization ongoing operations have long term strategies ongoing operations focus on multiple objectives ongoing operations don’t (normally) end!! PROJECTS vs. OPERATIONS Operations are existing systems and functions whereas Projects are one-time multi-disciplinary resource configuration. Operations focus on “Maintaining”, whereas Projects focus on “Change”. 3. Project management defined Project Management is the application of knowledge, skills, tools and techniques to project activities in order to meet or exceed project requirements(stakeholder needs and expectations from a project). It deals with tools, people, and systems. Project management cont’d The tools are work breakdown structures, PERT scheduling, earned value analysis, risk analysis, and scheduling software (to name a few). tools are the primary focus of most organizations that want to implement project management However, tools are a necessary but not a sufficient condition for success in managing projects Project management cont’d The processes are far more important, because if you do not employ the correct processes for managing, the tools will only help you document your failures with great precision. It is the people who run the processes. Organizations are people and people engage in processes to get the results Hence, project management calls for not only understanding techniques or operations of tools but understanding people management Project management cont’d Requirements are constraints on every project, no matter how large or how small They are defined by the PCTS targets P = performance requirements, technical (features of deliverable) and functional (what the deliverable is supposed to do) C = Cost to do the job T = time required for the project S = scope or magnitude of the work Project management cont’d The relationship between them may be given by the following expression: C = f(P, T, S) However, we are always estimating the values of these variables, so their exact relationship is never known. Literatures represent the relationship that exists between the PCTS constraints using a triangle where P, C, and T representing the lengths of the sides, while S representing the area. Project management cont’d What is important about this illustration is that one cannot arbitrarily assign values to all three sides and the area. If three are specified, the fourth can be determined, but if you try to assign values to all four, they will “fit” only by accident. It is common for the project sponsor or some other manager to want to dictate values for all four. This is, in fact, a common cause of project failures. Project management cont’d It is a project manager’s job to tell the sponsor what he or she needs if he/she to do a project. In this regard, the values for P, T, and S may be given by sponsor and the project manager may tell the sponsor the cost to achieve those targets. Project management cont’d (defn.2) Project management is accomplished through the application and integration of the project management processes of initiating, planning, executing, monitoring and controlling, and closing” From a project management perspective there are five main stages: Initiation Planning Execution Controlling and Wrap-up (close-out) Project management cont’d Initiation Phase: The need for a project is identified. An appropriate response to the need is determined and described. (This is actually where the project begins.) Issues of feasibility (can we do the project?) and justification (should we do the project?) are addressed. Project management cont’d The Planning Phase involves Defining the scope of the project Identifying intermediate work products (interim deliverables) along with the strategy for producing them. Definition of the required elements of work (tasks) and the optimum sequence for executing them (the schedule). Estimates are made regarding the amount of time and money needed to perform the work and when the work is to be done. Project management cont’d During the third phase, the Execution Phase, the prescribed work is performed under the watchful eye of the project manager. Progress is continuously monitored and appropriate adjustments are made and recorded as variances from the original plan. Throughout this phase, the project team remains focused on meeting the objectives developed and agreed upon at the outset of the project. Controlling: the act of comparing where you are to where you are supposed to be, so that corrective action can be taken when there is a deviation from the target. Project management cont’d During the final phase, or the Close-Out Phase, the emphasis is on verifying that the project has satisfied or will satisfy the original need. Ideally, the project culminates with a smooth transition from deliverable creation (the project) to deliverable utilization (the post-project life cycle). The project customer accepts and uses the deliverables. Throughout this phase, project resources (the members of the project team) are gradually redeployed and the project finally shuts down. Project management cont’d (defn.3) Project management is facilitation of the planning , scheduling, and controlling of all activities that must be done to meet project objectives Part II Project planning What planning is about? Planning – is the dynamic process of making decisions today about future actions; What missions or objectives be achieved, What actions should be taken, How the end can be achieved, When to achieve it, Who is to do it, Where to do it. It bridges the gap between where we are now and where we want to be. It gives bases for monitoring and evaluation of activities. Logical process (steps) in planning What is project planning? Project planning may be described as establishing a predetermined course of action within a forecasted environment. It involves: Identifying the tasks necessary to achieve a project goal, Estimating of required resources to accomplish the tasks, and Scheduling of people and tasks to meet the deadline. It expresses the objectives & requirements of the project in terms of project scope, project schedule, and resource requirement, project cost estimation, project quality, and project risk management. What is project planning cont’d? It’s often been said that project management really consists of two major phases—doing the right project and doing the project right. Ensuring that your project is based upon a true need and that it’s justified from a business standpoint are two important aspects of doing the right project. Project planning, on the other hand, is all about doing the project right. In essence, the project plan is a kind of map that you can use to guide you and your team from beginning to end. What is project planning cont’d? project planning is also an enormous subject mainly composed of strategic and tactical components(strategic vs. implementation planning) The strategic component consists of understanding some of the principles and philosophies of planning. The second component of project planning is tactical -almost mechanical It consists of the step-by-step process of creating a detailed project plan, using estimates as raw material. Project Planning as continuous Process project plans tend to emerge gradually. They are continuously modified and refined in terms of content, structure, and level of detail. As the project definition becomes more refined: work is broken down into ever-increasing levels of detail, assumptions are verified or refuted, and actual results are achieved, the project plan must keep pace _ continuous re-planning. Project Planning as continuous Process Planning Is Not a One-Time Event! As conditions change, your original plan must be modified to reflect those changes. The project plan is a living document and you should expect to be planning throughout the life of your project. Why project planning? To eliminate or reduce uncertainty To improve efficiency of the operation To obtain a better understanding of the objectives To provide a basis for monitoring and controlling work Beware! Common Planning Failures Failure to Plan- project managers feel (or are pressured into feeling) that planning is not worth doing at all. Failure to Plan in Sufficient Detail Failure to Know When to Stop Planning Failure to Involve Task Performers in Planning Failure to Reflect Risk and Uncertainty in Plans Failure to Keep the Plan Current. How Much Planning Is Enough? The answer to this question is … it depends: Organizational Expectations. Project Importance. Project Complexity. Project Size. Amount of Uncertainty. Planning and estimation Estimating is a big part and subset of project planning. To prepare reasonably accurate, thorough project plan, you’ll need to estimate many things: how long it will take to do the work, how much the work will cost, how much money the project will save or make, the magnitude of the risk and uncertainty involved, and other aspects of the project. Planning and estimation cont’d Estimation may be defined as “determining approximately the size, extent, value, cost, or nature of something.” The nature of project work is such that—even with significant prior experience—the uncertainty inherent in projects simply does not allow for absolute precision in estimates. Planning and estimation cont’d Some tips to make better estimation: Ask the person responsible for doing the work to prepare the estimate. Ask a subject matter expert—a person with knowledge or experience in that area. Use historical data and make appropriate adjustments. Use mockups, trial runs, tests, field studies, or other simulated experiences as a guide. Remember: estimates should reflect what you believe to be the most likely outcome. Planning and estimation cont’d Estimating Pitfalls Estimating is difficult. There are many things that can undermine the accuracy or validity of your estimates. Among the most common pitfalls are the following: Poorly defined scope of work. This can occur when the work is not broken down far enough or individual elements of work are misinterpreted. • Omissions. Simply put, you forget something. Planning and estimation: pitfalls cont’d Rampant optimism. This is the rose-colored glasses syndrome, when the all-success scenario is used as the basis for the estimate. Failure to assess risk and uncertainty- neglecting or ignoring risk and uncertainty can result in estimates that are unrealistic. • Time pressure. If someone comes up to you and says, “Give me a ballpark figure by the end of the day” and “Don’t worry, I won’t hold you to it,” look out! This almost always spells trouble. Failure to involve task performers. Preparing a Detailed Project Plan: Step by Step Preparing detail project plan involves various steps and can be grouped into: Project scope management (Identifying what needs to be done ) Project schedule development (part III) Project scope management what is scope and scope management in project context? What is scope? In the project context, the term scope may refer to: Product scope- the futures and functions that are to be included in a product or service Describes the product to be delivered –”what does the customer wants you to produce with the project?” The deliverables are products such as a new system, a new building, a new process, etc. Completion of the product is measured against product requirements that define the features or functions of the products. What is scope? Project scope- describes the work that must be done in order to deliver a product with the specified features and functions The first step in the planning process consists of identifying exactly what you’re going to do, the scope of work. In this stage, you identify major elements of work and then break them down systematically into smaller and smaller pieces, until each piece becomes a comfortable size to estimate, execute, and monitor. What is scope? The work representing project scope may comprise of various deliverables The deliverables can be meetings, reports, analysis, design documents, phases of project, etc. Completion of works under project scope is measured against the project scope management plan that is a subsidiary to the project management plan. What is scope? Project scope is a statement that defines the boundaries of the project Known with different names in different discipline: Functional specification- in information system Statement of work Document of understanding, Scoping statement, Project initiation document, Project request form. What is project scope management? Project scope management includes the process required to ensure that the project includes all the work required and only work required to complete the project successfully Primarily concerned with defining and controlling what is and is not included in the project This document is the foundation for all project work to follow. It is critical that scope be correct. Why? Project scope management processes Initiation –committing the organization to begin the next phase of the project Scope planning- developing a written scope statement as the basis for future project decisions Scope definition- subdividing the major project deliverables into smaller, and components more manageable Project scope management processes scope verification- formalizing acceptance of the project scope Scope change control- controlling change to project scope Note: though the project scope management processes appear here as a discrete elements with well defined interfaces, in practice they may overlap and interact 1. Initiation Project scope management requires consulting and understanding project initiation or authorization documents if any Initiation is the process of formally recognizing that a new project exists or that an existing project should continue into its next phase Formal initiation links the project to the ongoing work of the performing organization Feasibility study, preliminary plan or some other equivalent form of analysis proceeds formal initiation of the project in some organizations Initiation cont’d The initiation could be informal in other cases such as internal service projects and operational efficiency improvement project (eg, training project- EEPCO, ETC as a case in point) Inputs and outputs . Inputs: -product descriptions -project selection criteria -Strategic plan -Historical information Out puts -Project charter -Constraints -Assumptions -assignment of project manager Inputs to initiation Product descriptionthis documents the characteristics of a product or service that the project was undertaken to create The product description will generally have less detail in early phases and more detail in later ones as the product characteristics are progressively elaborated Inputs to initiation The product description should also document the relationship between the product being created and the business need or other stimuli that gave rise to the project While the form and substance of the product description will vary, it should always be detailed enough to support later project planning Inputs to initiation Strategic plan- all projects be supportive of the performing organization’s strategic goals – the strategic plan of the performing organization should be considered as a factor in project selection decision Project selection criteria- are typically defined in terms of the product of the project and can cover the full range of possible management concerns (financial return, market share, public perception, etc.) Inputs to initiation Historical information- information about both the results of previous project selection decisions and previous project performance should be considered to the extent it is available When initiation involves approval for the next phase of a project, information about the results of previous phases is often critical Outputs from initiation After considering these and other relevant inputs, a project may be formally authorized. This may be formalized through: Project charter- a document that formally recognizes the existence of a project It provides the project manager with the authority to apply organizational resources to project activities When a project is performed under contract, the signed contract will generally serve as the project charter for the seller Outputs from initiation cont’d Project manager identified/assigned: need to be done as early in the project as is feasible Constraints: are factors limiting the project management team’s options E.g., A pre-defined budget is a constraint that is highly likely to limit the team’s options regarding scope, staffing, and schedule When a project is performed under contract, contractual provisions will generally be constraints Outputs from initiation cont’d Assumptions: are factors that, for planning, purposes, will be considered to be true, real, or certain. E.g. If the date that a key person will become available is uncertain, the team may assume a specific start date Generally involve a degree of risk Note: events like producing project charter and assigning project manager marks formal recognition of a new project initiation or authorization. 2. Scope planning Scope planning is the process of developing a written scope statement Scope statement serves as the basis for future project decisions including, in particular, the criteria used to determine if the project or phase has been completed successfully A written scope statement is necessary for both projects and sub-projects It defines the boundaries of work Scope planning cont’d The scope statement forms the basis for an agreement between the project team and the project customer by identifying both the project objectives and the major product deliverables If all the elements of scope statement are already available (e.g., a request for proposal may identify the major deliverables, the project charter may define the project objectives) , this process may involve little more than physically creating the written document Accordingly, previous information or documents like product descriptions, project charter (contract), constraints (like project budget) and assumptions serve as inputs to project scope planning Outputs from scope planning The two main outputs of scope planning are: scope statement and scope management plan 1. Output: Scope statement Scope statement- provides a documented basis for making future project decisions and for confirming or developing common understanding of project scope among stakeholders May need to be revised or refined as project progresses to reflect changes to the scope of the project Contents of Scope statement The scope statement is supposed to include either directly or by reference to other documents: Project justification-the business need that the project was undertaken to address Project product- a brief summary of product description Contents of Scope statement cont’d Project deliverables- a list of the summary level sub- products whose full and satisfactory delivery marks completion of the project E.g. deliverables for a software development project might include: the working computer code, a user manual, and an interactive tutorial For organizational structure development project: alternative organizational structure, job description and specification document, HR policy manual, -- Contents of Scope statement cont’d When known, exclusions should be identified but anything not explicitly included is implicitly excluded Project objectives: the quantifiable criteria that must be met for the project to be successful Project objectives may include cost, schedule, and quality measures at minimum Contents of Scope statement cont’d Project objectives should have: an attribute- e.g., cost A yardstick – e.g., Birr and, An absolute or relative value – e.g., less than 2,000,000 Birr Note- in some areas, project deliverables are called project objectives while project objectives are called critical success factors Output: scope management plan Scope management plan: this document describes how project scope will be managed and how scope changes will be integrated into the project It should also include an assessment of the expected stability of the project scope- i.e., how likely it to change, how frequently, and by how much scope management plan cont’d The scope management plan should also include a clear description of how scope changes will be identified and classified Scope management plan may be formal or informal, highly detailed or broadly framed based on the needs of the project 3. Scope definition Involves subdividing the major project deliverables ( as identified in the scope statement) into smaller, more manageable components in order to: 1. improve the accuracy of cost, time, and resource estimates 2. define a baseline for performance measurement and control 3. Facilitate clear responsibility assignment Scope definition cont’d Proper scope definition is critical to project success When there is poor scope definition, final project cost is expected to be higher because of the inevitable changes which disrupt project rhythm , cause rework, increase project time, and lower the productivity and morale of the worker Input/output Inputs to scope definition Scope statement Constraints Assumptions Other planning outputs- the outputs of the processes in other knowledge areas should be reviewed for possible impact on project scope definition Historical information about previous projects should be considered – information about errors and omissions on previous projects is specially useful Tools and techniques for scope definition Work breakdown structure (WBS) templates A WBS from a previous project can often be used as a template for a new project Although project is unique, WBS can often be reused since most projects will resemble another project to some extent Decomposition- involves subdividing the major project deliverables into smaller, more manageable components until the deliverables are defined in sufficient detail to support future project activities: planning Executing, controlling, and closing Decomposition involves the following major steps: 1. identify the major elements of the project: In general, the major elements will be the project deliverables 2. Decide if adequate cost and duration estimates can be developed at this level of detail for each element The meaning of adequate may change over the course of the project- decomposition of a deliverable that will be produced far in the future may not be possible For each element, proceed to step 4 if there is adequate detail and to step 3 if there is not- this means that different elements may have deferring levels of decomposition 3. identify constituent elements of the deliverable Constituent elements should be described in terms of tangible, verifiable results in order to facilitate performance measurement Should be defined in terms of how the work of the project will actually be accomplished Tangible, verifiable results can include services as well as products ( e.g., status reporting could be described as a weekly status reports; for manufactured item, constituent elements might include several individual components plus final assembly Repeat step 2 on each constituent element 4. verify the correctness of the decomposition: Are the lower-level items both necessary and sufficient for completion of the item decomposed? If not, the constituent elements must be modified (added to or deleted from or redefined) Is each item clearly and completely defined? If not the descriptions must be revised or expanded Can each item be appropriately scheduled? Budgeted? Assigned to specific organizational unit such as department, team, or person- who will accept responsibility for satisfactory completion of the item? If not, revisions are needed to provide adequate management control Outputs from scope definition Scope definition results in Work Breakdown Structure (WBS) What is WBS? WBS cont’d WBS is a deliverable-oriented grouping of project elements that organizes and defines the total scope of the project WBS is a deliverable-oriented hierarchical decomposition of the work to be executed by the project team to accomplish the project objectives and create the required deliverables. Work not in the WBS is outside the scope of the project As with the scope statement, the WBS is often used to develop or confirm a common understanding of project scope WBS cont’d The items at the lowest level of WBS are often referred to us work packages It is the point at which the cost and schedule can be reliably estimated. The level of detail for Work Packages will vary with the size and complexity of the project. WBS cont’d It represents an explicit description of the project‘s scope, deliverables and outcomes—the “what‘‘ of the project. However, the WBS is not a description of the processes followed to perform the project . . . nor does it address the schedule that defines how or when the deliverables will be produced. Rather, the WBS is specifically limited to describing and detailing the project‘s outcomes or scope. WBS cont’d It is a foundational project management component, and as such is a critical input to other project management processes and deliverables such as: activity definitions, project network diagrams, project and program schedules, performance reports, risk analysis and response, control tools or project organization. WBS cont’d WBS is normally presented in chart form Each item in the WBS is generally assigned a unique identifier: these identifiers are often known collectively as code accounts Work element descriptions are often collected in a WBS dictionary WBS Dictionary will typically include work package descriptions as well as other planning information such as schedule dates, cost budgets, and staff assignments WBS cont’d Note: WBS should not be confused with other kinds of “breakdown” structures used to present project information- such as: Contractual WBS (CWBS)- which is used to define the level of reporting that the seller will provide the buyer Organizational breakdown structure (OBS), which is used to show which work elements have been assigned to which organizational units WBS cont’d Resource breakdown structure (RBS), which is a variation of the OBS and is typically used when work elements are assigned to individuals Bill of materials (BOM), which presents a hierarchical view of the physical assembles, subassemblies, and components needed to fabricated a manufactured product Project breakdown structure (PBS), which fundamentally the same as a properly done WBS. The term PBS is widely used in application areas where the term WBS is incorrectly used to refer to a BOM WBS cont’d: Creating WBS: There is no ―right‖ way to construct a WBS. The full scope of work for the project is placed at the top of the diagram, and then sub-divided smaller elements of work at each lower level of the breakdown. Each descending level represents an increasingly detailed description of the project elements At the lowest level of the WBS the elements of work is called a work package. A list of project‘s activities is developed from the work packages. key characteristics of high-quality WBS 1. WBS is that it is “deliverable oriented‘‘. Here a deliverable is defined as any unique and verifiable product, result, or capability to perform a service that must be produced to complete a process, phase or project. In this context, oriented means aligned or positioned with respect to deliverables (i.e., focused on deliverables). Deliverable oriented WBS 2. An additional key attribute of the WBS is that it is a hierarchical decomposition of the work. Is hierarchical and constructed in such a manner that (a) each level of decomposition includes 100% of the work of its parent element, and (b) each parent element has at least two child elements Hence decomposition process need to confirm to the 100% Rule 100% rule states that the WBS includes 100% of the work defined by the project scope and, by doing so, captures all deliverables in terms of work to be completed The rule applies at all levels within the hierarchy; the sum of the work at the “child‘‘ level must equal 100% of the work represented by the “parent‘‘. The WBS should not include any work that falls outside the actual scope of the project; that is, it cannot include more than 100% of the work. 3. Includes only those elements to be delivered by the project (and nothing that is considered out of scope) 4. Uses noun and adjective to describe the deliverables, not verb-objective format 5. Employs a coding scheme that clearly depicts the hierarchical nature of the project 6. Includes a WBS Dictionary that describes and defines the boundaries of the WBS elements 7. Contains work packages that clearly support the identification of the tasks, activities and milestones that must be performed in order to deliver the work package 8. Is updated in accordance with project change management procedures Task oriented WBS Why in terms of deliverables? With task-oriented Work Breakdown Structures, the focus will be on process or action This implies that the true end-product of the WBS element is a refined process rather than the actual deliverables of the process. The performance of the process, rather than outputs, becomes the focus of the work, and as such it is possible to perform the process flawlessly without ever producing specific deliverables Hence, it is advisable to state WBS in terms of noun and adjective rather than in terms of verb-objective Coding WBS Coding scheme is a critical element to quality Work Breakdown Structures It should clearly show the parent-child relationship or the level on the chart previous WBS: The top of the chart reflects the project level and is coded with a 1. The next level of decomposition, level 2, is broken down into 1.1, 1.2, 1.3 and 1.4. Coding WBS Coding scheme is a critical element to quality Work Breakdown Structures It should clearly show the parent-child relationship or the level on the chart previous WBS: The top of the chart reflects the project level and is coded with a 1. The next level of decomposition, level 2, is broken down into 1.1, 1.2, 1.3 and 1.4. 4. Scope verification Is the process of formalizing acceptance of the project scope by the stakeholders (sponsor, client, customer, etc.) Requires reviewing work products and results to ensure that all were completed correctly and satisfactorily If the project is terminated early, the scope verification process should establish and document the level and extent of completion Scope verification differs from quality control in that it is primarily concerned with acceptance of the work results while quality control is primarily concerned with the correctness of the work results Inputs to scope verification 1. Work results: work results- which deliverables have been fully or partially completed, what costs have been incurred or committed, etc. are an output of project plan execution 2. product documentation. Documents produced to describe the project’s products must be available for review The terms used to this documentation (plans, specifications, technical documentation, drawings, etc.) vary by application area Tools and techniques for scope verification Inspection It includes activities such as measuring, examining, and testing undertaken to determine whether results confirm to requirements Known with names such as reviews, product reviews, audits, walk- through Outputs from scope verification Formal acceptance Documentation that the client or sponsor has accepted the product of the project or phase must be prepared and distributed Such acceptance may be conditional, specially at the end of a phase 5. Scope change control Scope change control is concerned with 1. influencing the factors which create scope changes to ensure that changes are beneficial 2. determining that a scope change has occurred , and 3. managing the actual changes when and if they occur Scope change control must be thoroughly integrated with other control processes such as Time control Cost control Quality control Inputs to scope change control A. WBS B. Performance reports- provides information on scope performance such as which interim products have been completed and which have not Performance reports may also alert the project team to issues which may cause problems in the future C. Change requests Changes may require expanding the scope or may allow shrinking it Change requests may occur in many forms such as: Oral or written Direct or indirect Externally or internally initiated Legally mandated or optional Most change requests are the result of: An external event – e.g., a change in a government regulation An error or omission in defining the scope of the product- e.g., failure to include a required future in the design A value-adding change (taking cost reduction advantage brought by new technology which was not at the time when the scope was originally defined) D. The scope management plan in general can be an input to scope change control Tools and techniques for scope change control Scope change control system- defines the procedures by which the scope may be changed- may include paper work, tracking systems, approval levels needed for authorization Additional planning Outputs from scope change control Scope change – is any modification to the agreed-upon project scope as defined by the approved WBS Often requires adjustments to cost, time, quality, and related project objectives Corrective action- anything done to bring expected future project performance into line with the project plan Lessons learned- the cause of variance, the reasoning behind the corrective action chosen, and other types of lessons learned from scope change control should be documented so that this information becomes part of the historical database for both the project and other projects of the performing organization
