Marchewka Northern Illinois University Power Point Slides by Gerald DeHondt Grand Valley State University 10-1 Copyright 2012 John Wiley & Sons, Inc. IT Project Quality Management Chapter 10 10-2 Copyright 2012 John Wiley & Sons, Inc. Learning Objectives Describe the Project Management Body of Knowledge (PMBOK®) area called project quality management (PQM) and how it supports plan quality, perform quality assurance, and perform quality control to provide continuous improvement of the project’s products and supporting processes. Identify several quality gurus, or founders of the quality movement, and their role in shaping quality philosophies worldwide. Describe some of the more common quality initiatives and management systems that include ISO certification, Six Sigma, and the capability maturity model (CMM) for software engineering. Distinguish between validation and verification activities and how these activities support IT project quality management. Describe the software engineering discipline called configuration management and how it is used to manage the changes associated with all of the project’s deliverables and work products. Apply the quality concepts, methods, and tools introduced in this chapter to develop a project quality plan. 10-3 Copyright 2012 John Wiley & Sons, Inc. What is Quality? “an inherent or distinguishing characteristic; a property; having a high degree of excellence” Features & functionality 10-4 “fitness for use” “conformance to requirements” Copyright 2012 John Wiley & Sons, Inc. PMBOK® – Project Quality Management (PQM) Project Quality Management includes the processes and activities of the performing organization that determine quality policies, objectives, and responsibilities so that the project will satisfy the needs for which it was undertaken. It implements the quality management system through policy and procedures with continuous process improvement activities conducted throughout, as appropriate. 10-5 Copyright 2012 John Wiley & Sons, Inc. PMBOK® – PQM Processes Plan Quality Determining which quality requirements and/or standards are important for the project and the product and then documenting how compliance will be demonstrated. Perform Quality Assurance Provides the basis for continuous improvement by auditing and evaluating the results from quality control measurements so that appropriate quality standards and operational definitions are used. Perform Quality Control Monitoring and documenting the results of executing project quality activities to eliminate causes of unsatisfactory performance and implement new processes and techniques to improve project quality throughout the organization. 10-6 Copyright 2012 John Wiley & Sons, Inc. PQM Focuses on The project’s products Business Case Project Plan The IT Solution Etc. And the project’s processes 10-7 Scope management Risk management Requirements Analysis Design Implementation Etc. Copyright 2012 John Wiley & Sons, Inc. The Quality Chain More efficient & effective use of resources Minimize errors Meet or exceed stakeholder expectations More rework, waste, & errors Negative impact on project goal & objectives Poor quality can be an embarrassment! Project and IT development processes support the project’s products Customers may be internal or external 10-8 Copyright 2012 John Wiley & Sons, Inc.

Scientific Management Fredrick W. Taylor (1856 – 1915) Management would set arbitrary rules of thumb Workers produced so much each day – no more, no less Believed the production process could be more efficient Break a task down into smaller tasks & study it to find the best and most efficient way of doing it Time – motion studies 10-11 Did not sit well with labor unions because many ignored the human factors & believed profits could be increased by speeding up the workers Copyright 2012 John Wiley & Sons, Inc. Control Charts Walter A. Shewhart (1891 – 1967) Worked for Western Electric Company (Bell Telephones) Quality improvements needed for underground equipment Applied statistical theory to control production processes 10-12 Copyright 2012 John Wiley & Sons, Inc. The Total Quality Movement W. Edwards Deming (1900 – 1993) Worked with Shewhart at Western Electric Hawthorne Plant in Chicago, IL in the 1920s Management treated the worker as a cog in the machinery Final inspection used to control quality Worker not directly responsible Scrap & rework reduced per piece rate 10-13 Invited to give series of day-long lectures in Japan in the 1950s Copyright 2012 John Wiley & Sons, Inc. Deming’s 14 Points 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. Have a purpose (improve products and services, be competitive, stay in business, and provide jobs). Adopt the new philosophy of management. Don’t depend on inspection at the end. Don’t award business based on price tag. Keep improving constantly. Institute training on the job. Institute leadership. Drive out fear. Break down barriers between departments. Eliminate slogans. a) Eliminate quotas. b) Eliminate management by objective and by numbers. Take pride in your work. Focus education and self-improvement. It takes everyone to accomplish the transformation. From Out of the Crisis by W. Edwards Deming (1986) 10-14 Copyright 2012 John Wiley & Sons, Inc. Quality Planning, Improvement, & Control Joseph Juran (1904 - 2007) Viewed quality as “fitness for use” Also invited to Japan to conduct seminars in the 1950s Message is that quality does not happen by accident – it must be planned in 10-15 Copyright 2012 John Wiley & Sons, Inc. Quality Planning, Improvement, & Control Juran’s Quality Planning Road Map (Quality Trilogy) Quality Planning 1. Identify who are the customers. 2. Determine the needs of those customers. 3. Translate those needs into our language. 4. Develop a product that can respond to those needs. 5. Optimize the product features so as to meet our needs as well as customer needs. Quality Improvement 6. Develop a process that is able to produce the product. 7. Optimize the process. Quality Control 8. Prove that the process can produce the product under operating conditions. 9. Transfer the process to Operations. 10-16 Copyright 2012 John Wiley & Sons, Inc. Cause & Effect Diagrams, Pareto Charts, and Flow Charts Kaoru Ishikawa (1915 - 1989) Studied under Deming Believed quality is a continuous process that relies on all levels of the organization Advocated the use of easy-to-use statistical tools 10-17 Ishikawa, or Fishbone Diagram Pareto Diagram Flow Charts Copyright 2012 John Wiley & Sons, Inc.

ISO International Organization for Standardization (ISO) Derived from Greek word “isos,” meaning “equal” Formed in 1947 Today has over 130 members “to facilitate the international coordination and unification of industrial standards.” Standards make up the ISO 9000 (organizations) and ISO 14000 (environmental) families 10-22 Copyright 2012 John Wiley & Sons, Inc. 6-Sigma Originated by Motorola in Schaumburg, IL Based on competitive pressures in 1980s – “Our quality stinks” Sigma Defects Per Million 3δ 6δ 1δ 690,000 2δ 308,537 Five short or long landings at any major airport One short or long landing in 10 years at all airports in the US 3δ 66,807 4δ 6,210 Approximately 1,350 poorly performed surgical operations in one week One incorrect surgical operation in 20 years 5δ 233 Over 40,500 newborn babies dropped by doctors or nurses each year Three newborn babies dropped by doctors or nurses in 100 years 6δ 3.4 Drinking water unsafe to drink for about 2 hours each month Water unsafe to drink for one second every six years 10-23 Copyright 2012 John Wiley & Sons, Inc. 6-Sigma D-M-A-I-C Cycle Define Measure With data in hand, the team can analyze the data for trends, patterns, or relationships. Statistical analysis allows for testing hypotheses, modeling, or conducting experiments. Improve The Six Sigma team is responsible for identifying a set of relevant metrics. Analyze The first step is to define customer satisfaction goals and subgoals; for example, reduce cycle time, costs, or defects. These goals then provide a baseline or benchmark for the process improvement. Based on solid evidence, improvements can be proposed and implemented. The MeasureAnalyze-Improve steps are generally iterative to achieve target levels of performance. Control Once target levels of performance are achieved, control methods and tools are put into place in order to maintain performance. 10-24 Copyright 2012 John Wiley & Sons, Inc. 6-Sigma Roles & Responsibilities Master black belts Black belts Should be technically competent and held in high esteem by their peers. They are actively involved in the Six Sigma change process. Green belts People within the organization who have the highest level of technical and organizational experience and expertise. Master black belts train black. Are Six Sigma team leaders or project managers. Black belts generally help green belts choose their projects, attend training with them, and then assist them with their projects once the project begins. Champions Leaders who are committed to the success of the Six Sigma project and can ensure that barriers to the Six Sigma project are removed. Usually a high-level manager who can remove obstacles that may involve funding, support, bureaucracy, or other issues that black belts are unable to solve on their own. 10-25 Copyright 2012 John Wiley & Sons, Inc. The Capability Maturity Model Integration (CMMI) Developed by the Software Engineering Institute at Carnegie Mellon University in 1986 Mitre Corporation and Watts Humphrey developed a framework to assess and evaluate the capability of software processes and their maturity Called the Capability Maturity Model (CMM), but has evolved to the CMMI which is not limited to a specific area but can be used across different disciplines 10-26 Copyright 2012 John Wiley & Sons, Inc. Immature Software Organization Software processes are improvised Or not followed! Managers continually “fight fires” No basis for judging quality Schedules & budgets are usually exceeded Functionality & quality often compromised to meet schedules 10-27 Copyright 2012 John Wiley & Sons, Inc. Mature Software Organization Has organization-wide ability to manage software development Software process is communicated to staff Processes are consistent with the way work gets done Processes are updated when necessary Roles & responsibilities are well-defined 10-28 Copyright 2012 John Wiley & Sons, Inc. Other CMMI Concepts Software process A set of activities, methods, or practices and transformations used by people to develop and maintain software and the deliverables associated with software projects. Included are such things as project plans, design documents, code, test cases, user manuals, and so forth. Software process capability The expected results that can be achieved by following a particular software process. More specifically, the capability of an organization’s software processes provides a way of predicting the outcomes that can be expected if the same software processes are used from one software project to the next. Software process performance The actual results that are achieved by following a particular software process. Therefore, the actual results achieved through software process performance can be compared to the expected results achieved through software process capability. Software process maturity The extent to which a particular software process is explicitly and consistently defined, managed, measured, controlled, and effectively used throughout the organization. 10-29 Copyright 2012 John Wiley & Sons, Inc. Levels of Software Process Maturity 10-30 Copyright 2012 John Wiley & Sons, Inc. CMMI Level 1: Initial Characterized by an immature software organization in which the software process is ad hoc and often reactive to crises. Does not have a stable environment for software projects, and success of a project rests largely with the people on the project and not the processes that they follow. Key Process Area no key process areas are in place 10-31 Copyright 2012 John Wiley & Sons, Inc. CMMI Level 2: Repeatable - Basic policies, processes, and controls for managing a software project are in place. Previous project successes can be repeated by other project teams on other projects. Key Process Area 10-32 Software Configuration Management Software Quality Assurance Software Subcontract Management Software Project Tracking and Oversight Software Project Planning Requirements Management Copyright 2012 John Wiley & Sons, Inc. CMMI Level 3: Defined - Software engineering and management processes are documented and standardized throughout the organization and become the organizations standard process. Key Process Area 10-33 Peer Reviews Intergroup Coordination Software Product Engineering Integrated Software Management Training Programs Organization Process Definition Organization Process Focus Copyright 2012 John Wiley & Sons, Inc. CMMI Level 4: Managed - Quantitative metrics for measuring and assessing productivity and quality are established for both software products and processes which are characterized as being quantifiable and predictable. Key Process Areas 10-34 Software Quality Management Quantitative Process Management Copyright 2012 John Wiley & Sons, Inc. CMMI Level 5: Optimizing at the highest level of software process maturity, the whole organization is focused on continuous process improvement. Key Process Areas 10-35 Process Change Management Technology Change Management Defect Prevention Copyright 2012 John Wiley & Sons, Inc. The IT Project Quality Plan 10-36 Copyright 2012 John Wiley & Sons, Inc. Quality Philosophies & Principles Focus on customer satisfaction Prevention, not inspection Improve the process to improve the product Quality is everyone’s responsibility Fact-based management 10-37 Copyright 2012 John Wiley & Sons, Inc. Developing Standards & Metrics 10-38 Copyright 2012 John Wiley & Sons, Inc. Project Quality Metrics Process Control the defects introduced by the processes required to create the project deliverables Can be used to improve software development or maintenance Should focus on the effectiveness of identifying and removing defects or bugs Product Focuses on the intrinsic quality of the deliverables and satisfaction of the customer, client, or sponsor with these deliverables Attempt to describe the characteristics of the project’s deliverables and final product Project Focus on the control of the project management processes to ensure that the project meets its overall goal as well as its scope, schedule, and budget objectives 10-39 Copyright 2012 John Wiley & Sons, Inc. Process, Product, & Project Metrics Examples Type Process Product Project 10-40 Metric Description Defect Arrival Rate The number of defects found over a specific period of time. Defects by Phase The number of defects found during each phase of the project. Defect Backlog The number of defects waiting to be fixed. Fix Response Time The average time it takes to fix a defect. Defective Fixes The number of fixes that created new defects. Mean Time to Failure Average or mean time elapsed until a product fails. Defect Density The number of defects per lines of code (LOC) or function points. Customer Found Defects The number of defects found by the customer.

Verification & Validation (V&V) Verification Focuses on process-related activities to ensure that the products & deliverables meet specified requirements before final testing Technical Reviews Walk-throughs Business Reviews Management Reviews Are we building the product the right way? 10-41 Copyright 2012 John Wiley & Sons, Inc. Verification & Validation (V&V) Validation Product-oriented activities that attempt to determine if the system or project deliverables meet the customer or client’s expectations Testing Does the system function as intended and have all the capabilities & features defined in the project’s scope and requirements definition Did we build the right product? 10-42 Copyright 2012 John Wiley & Sons, Inc. Software Testing Approaches Unit Testing Focuses on the module, program, or object level to determine whether specific functions work properly. •Black Box Testing – Tests the program against specified requirements or functionality. •White Box Testing – Examines paths of logic or the structure inside a program. •Gray Box Testing – Focuses on the internal structure of the program. Integration Testing Tests whether a set of logically related units (e.g., functions, modules, programs, etc.) work together properly after unit testing is complete. Systems Testing Tests the system as a whole in an operating environment to verify functionality and fitness for use. May include tests to verify usability, performance, stress, compatibility, and documentation. Acceptance Testing 10-43 Certifies that the system satisfies the end user or customer’s scope and detailed requirements after systems testing is complete. It is the user’s or client’s responsibility to assure that all features and functionality are included so that the project’s MOV will be achieved. Copyright 2012 John Wiley & Sons, Inc. Change, Control, & Configuration Management Changes to the project work must be managed What changes were made? Who made the changes? When were the changes made? Why were the changes made? Configuration management includes a set of processes and tools that allow the project team to manage its various documents and files as various configurations of IT solutions and project deliverables are derived. It may include specifying and enforcing various policies that restrict access to specific individuals or preventing two people from changing the same document or file at the same time. 10-44 Copyright 2012 John Wiley & Sons, Inc. Quality Control Activities Quality Control Activities should focus on the inputs and outputs of each process. 10-45 Copyright 2012 John Wiley & Sons, Inc. Learn, Mature, and Improve Lessons learned Provide the basis for continual improvement Can be the basis for identifying and implementing best practices A quality plan should do more that attempt to build a better IT solution, it should also support the organization in searching for ways to manage projects better. 10-46 Copyright 2012 John Wiley & Sons, Inc.
