Learning Objectives Define Agile and Scrum Articulate the benefits of being Agile Describe the principles of the Agile Manifesto Describe the principle of continuous improvement applied to a Scrum adaptation Two Approaches of Project Management Waterfall Approach Agile Approach It involves big planning upfront to: • Agile approach is appropriate • Determine the detailed scope of for complex and uncertain the project • Establish the project’s performance baselines projects • An Agile project evolves as short increments are completed Definition of Agile “Agile is an iterative and incremental evolutionary approach to project development which is performed in a highly collaborative manner by self-organizing teams with just enough ceremony that produces high-quality software in a cost effective and a timely manner which meets the changing needs of its stakeholders.” —Scott Ambler, a thought leader in the Agile world Evolution of Agile Manifesto Evolution of Agile from a family of light weight, quality-driven approaches to software development Feb 2001 Late 1990’s Agile Manifesto signed by 17 leading software developers Agile Manifesto “We are in covering better ways of developing software by doing it and helping others do it. Through this work we have come to value: 1. Individuals and interactions over processes and tools 2. Working software over comprehensive documentation 3. Customer collaboration over contract negotiation 4. Responding to change over following a plan That is, while there is value in the items on the right, we value the items on the left more.“ —Agile Manifesto Understanding Agile Manifesto Individuals and interactions Working software Customer collaboration Responding to change over Process and tools over Comprehensive documentation over over Contract negotiation Following a plan Individuals and their interactions deliver better results when the emphasis is NOT on the processes and the tools. Emphasis on working software can deliver real progress or value. Organizations need to be accommodating rather than following detailed definitions listed in contracts. Customer suggestions must be incorporated to deliver the value the customers want. The 12 Principles of Agile Software There are 12 guiding principles that support the Agile Manifesto: 1 Our highest priority is to satisfy the customer through early and continuous delivery of valuable software. 2 Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage. 3 Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter time scale. 4 Business people and developers must work together daily throughout the project. 5 Build projects around motivated individuals. Give them the environment and support they need and trust them to get the job done. 6 The most efficient and effective method of conveying information to and within a development team is face-to face-conversation. The 12 Principles of Agile Software (Contd.) 7 Working software is the primary measure of progress. 8 Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely. 9 Continuous attention to technical excellence and good design enhances agility. 10 Simplicity, the art of maximizing the amount of work not done, is essential. 11 The best architectures, requirements, and designs emerge from self-organizing teams. 12 At regular intervals, the team reflects on how to become more effective and then tunes and adjusts its behavior accordingly. Scrum In 1986, Scrum was first introduced by Hirotaka Takeuchi and Ikujiro Nonaka. SCRUM It was a new approach to commercial product development that would increase speed and flexibility.

Advantages of Scrum Scrum is a proven Agile software development methodology that provides significant benefits over the traditional waterfall approach. High productivity and low cost due to less waste and reduced cost of rework Improved stakeholder satisfaction due to greater adaptability Higher quality by establishing clear acceptance criteria and “Definition of Done” Improved employee engagement and job satisfaction due to sustainable pace, self-organization, and delivery of high-quality products Faster time-to-market by delivering incrementally Note: For information on “Agile project management process framework,” refer to complex process framework.pdf in Additional Information.zip in the download section. Popularity of Scrum Scrum is a leading agile methodology. More than 50% of Agile projects use it. Features that make scrum so popular include the following: Offers simplicity and proven results Encompasses other Agile engineering techniques Emphasizes small teams and team empowerment Welcomes changes to requirements Allows working from a single source of prioritized work items Includes daily status meetings Offers team commitment to potentially shippable software at the end of each Sprint Agile Methods Deliver Value Faster Iteration 6 Iteration 5 Iteration 4 Delivered Value Delivered Value The chart illustrates how Agile methods deliver value faster than expensive traditional methods. Iteration 3 Iteration 2 Iteration 1 Agile Iterative Delivery Time Project Delivered Time Non-Agile Iterative Delivery Understanding the Impact of Scrum It is important to definitively answer the following questions to understand the impact of Scrum. Has the investment in Scrum paid off? What is our next area of improvement? Should we continue with Scrum? Are we better than before? Are we producing better products? Do our products have fewer defects? Are we able to ship faster than before? Testing and measuring the results of any effort helps to discover the success. Key Takeaways Agile is an iterative and incremental method for developing products. Scrum is the most popular Agile framework. It is composed of transparency, inspection, and adaptation. Scrum provides value to the organization in the form of higher productivity, reduced cost, better quality, and engaged and satisfied employees. Scrum helps in faster time-to-market and improved stakeholder satisfaction. Scrum relies on frequent feedback and experimentation, resulting in better predictability and flexibility. The actual results of Scrum adoption should be tested and measured. Quiz QUIZ 1 Which of the following would be considered most valuable by an Agile team? a. Following a plan b.
