Exercise “Continuum” Agile Software Development with 6 SCRUM ©SCRUMguides

Project successes/failures Have you been on a successful project? Have you been on an unsuccessful project? Agile Software Development with 8 SCRUM ©SCRUMguides

Agile might help you, let’s see… Understanding Agile and SCRUM Agile Software Development with 9 SCRUM ©SCRUMguides

The two approaches, two cultures Predictive approach Sees projects as predictive processes which results can be foreseen (predicted) with acceptable probability after reasonable planning and study efforts spent. Adaptive approach Questions predictability of projects due to their built-in complexity. It puts stress on steering based on observations. Agile Software Development with 10 SCRUM ©SCRUMguides

The predictive approach Release Design spec Requirements spec Order C D Actual need P P R Agile Software Development with 11 SCRUM ©SCRUMguides

The adaptive approach When in the project we 100% know if we on/off the track in terms of the time, scope, costs…? Vision C Actual need Agile Software Development with 12 SCRUM ©SCRUMguides

The two approaches to project management Predictive approach Heavy-weight; – Process-oriented; – Plan-driven; – “Waterfall”. – Adaptive approach Light-weight; – People-oriented; – Value-driven; – “Agile”. – Agile Software Development with 13 SCRUM ©SCRUMguides

Order and Chaos Agile Software Development with 14 SCRUM ©SCRUMguides

The cone of uncertainty SCRUM decreases the chaos by fixing the scope Agile Software Development with 15 SCRUM ©SCRUMguides

The two approaches on the time scale Which advantages/disadvantages of the approaches you see? Agile Software Development with 16 SCRUM ©SCRUMguides

Agile and SCRUM SCRUM – one of the Agile approaches. It is a project framework, or a set of recommendations by following which you can increase the chance of successful ending of your projects. Agile Software Development with 17 SCRUM ©SCRUMguides

Agile Manifesto We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value: Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation 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 Software Development with 18 SCRUM ©SCRUMguides

Principles of Agile Manifesto Please see www.agilemanifesto.org for the twelve principles Agile Software Development with 19 SCRUM ©SCRUMguides

Main aspects of Agile Agile Software Development with 20 SCRUM ©SCRUMguides

The main aspects of Agile Team Work Prioritization Short cycles Learn and Adapt Agile Software Development with 21 SCRUM ©SCRUMguides

The main aspects of Agile: Team work What is a team? Agile Software Development with 22 SCRUM ©SCRUMguides

Team work (cont.) Exercise “an airplane factory”. Agile Software Development with 23 SCRUM ©SCRUMguides

Push vs. Pull systems SCRUM is a pull system Agile Software Development with 24 SCRUM ©SCRUMguides

Team work (cont.) What is a team? Are you in a good team? How to become a greater team? How to evaluate and motivate people’s work in a team? Agile Software Development with 25 SCRUM ©SCRUMguides

Is here such a thing as “team work”? Release Design spec Requirements spec Order C D Actual need P P R Agile Software Development with 26 SCRUM ©SCRUMguides

A SCRUM team is A cross-functional group of people (5-9 members) responsible for managing itself to develop the product. Agile Software Development with 27 SCRUM ©SCRUMguides

Prioritization and Traditional approaches An alternative tool to backlogs are requirement specifications. Agile Software Development with 29 SCRUM ©SCRUMguides

“Gimme all requirements, or ….” Agile Software Development with 30 SCRUM ©SCRUMguides

As a result … As a result all requirements are the “top priority”. Which is basically the same as not having the priorities at all. Agile Software Development with 31 SCRUM ©SCRUMguides

And as a result … Agile Software Development with 32 SCRUM ©SCRUMguides

What does it mean to us? As a consequence: we can cut costs and duration of our projects in 2/3! Does it mean we (the teams) will earn less money? Agile Software Development with 33 SCRUM ©SCRUMguides

What about your projects? Think about your current (recent) projects. List 5-10 features that could have been avoided or simplified by keeping the product as good as it was. What would be your % of rarely/never used features? Agile Software Development with 34 SCRUM ©SCRUMguides

Prioritize (cont.) YAGNI - “You ain’t gonna need it”. A strategy of postponing decisions until the last possible moment. Product backlog Just-in-time requirements management tool. Agile Software Development with 36 SCRUM ©SCRUMguides

The “menu” (Agile) approach Product backlog is the project’s menu. “Servants” help to make better decisions. Agile Software Development with 37 SCRUM ©SCRUMguides

What saves our projects? “The features that we manage to de-scope are the savers of our projects” © Kent Beck Agile Software Development with 38 SCRUM ©SCRUMguides

Today’s Agenda Opening: program overview, knowing each other Understanding Agile and SCRUM till 16:00 Coffee break 16:00 – 16:30 SCRUM simulation 16:30 – 17:30 Extra SCRUM topics 17:30 – 18:00 Agile Software Development with 39 SCRUM ©SCRUMguides

The main aspects of Agile: Short Cycles The shorter the cycle the more efficient the process We have more time to “play” with the product that 1. we are developing; The sooner we can catch a defect the easier it is to 2. fix it; The shorter the cycle (the smaller a batch of work) 3. the less need we have in creating intermediate artifacts. Agile Software Development with 41 SCRUM ©SCRUMguides

Iterative and Incremental approach How do you eat an elephant? - One bite at a time! - Agile Software Development with 44 SCRUM ©SCRUMguides

Shorter Cycles = Faster Feedback Daily meetings 1. Code Reviews 2. Release to end-users 3. Iteration reviews 4. Continuous integration 5. Feedback from (onsite) clients 6. Unit-testing 7. (Automated) acceptance testing 8. Pair programming 9. Agile Software Development with 45 SCRUM ©SCRUMguides

Shorter Cycles = Faster Feedback (ordered) Pair programming (immediate feedback) Unit-testing (5-10 minutes) Continuous integration (hourly) Feedback from (onsite) clients (daily) Daily meetings (daily) Code Reviews (some days) (Automated) acceptance testing (some days) Iteration reviews (each second week) Release to end-users (some weeks-months) Agile Software Development with 46 SCRUM ©SCRUMguides

The main aspects of Agile: Learn and Adapt As we work we learn lots of new things about the product being developed, technologies being used, our clients, ourselves. By incorporating this information into daily work we can become better day by day. Agile Software Development with 49 SCRUM ©SCRUMguides

Visibility tools In order to evolve the way we work we need to keep everything visible to ourselves and our clients Tools that might help: Sprint Burndown Chart Task boards Wikis Agile Software Development with 50 SCRUM ©SCRUMguides

Game structure Planning Choose a product and your PO Help your PO to build up a PB Help your PO to prioritize the PB items Plan your first sprint Sprinting Day one - 7 min Daily standup - 3 min Day two - 7 min Demonstration - 3 min (per a team) Agile Software Development with 58 SCRUM ©SCRUMguides
