Agile lean software development principles

  1. 1. Agile Software Development (Lean Software Development Method) HAIRINA BINTI HAMDZAH September 15, 2015
  2. 2. Introduction Agile Software Development • Agile – able to move quickly and easily • Agile software development – process that support the agile philosophy • Philosophy- • Suitable for - - Small or medium size scale - Custom system development within organization • Other agile software development – XP, Scrum, kanban method, Crystal Family and many more
  3. 3. Lean Software Development • Implementation of a lean manufacturing principles into a software development model • Lean manufacturing principle originated from Toyota production system in Japan • Main objective: Reduce waste in a system and produce a higher value for the customer
  4. 4. Key Principles of Lean Software Development Eliminate waste Build in integrity Amplify Learning Defer commitment Deliver fast Respect people Optimize the whole
  5. 5. Principal 1: Eliminate waste – Waste: anything that didn’t improve quality of code, didn’t reduce time and effort in development process and didn’t provide real value too customer (tools:VSP mapping) – Three types of waste Waste in code development Waste in project management Waste in workforce potential Principal 2: Amplify Learning – Softw. Development is a continuous learning process (need to learn as project develop) – Predictable performance is driven by feedback
  6. 6. Principal 3: Defer Commitment – Deciding irreversible decision as late as possible to keep option open for as long as practical – Why? ->The later the decision are made, the more information we will have to make the right decision. *important of timeboxs – >adaptable, change is manageable – >avoid/ delay cost of change Principal 4: Deliver Fast – Customer like a rapid deliver – Less time for a customer to change their mind – Avoid over-enginered solution – Complement defer commitment
  7. 7. Principal 5: Respect People – Empower those who add value: letting people who add value use their full potential – To get individual to be motivated and take responsibility -> be responsible for the outcome and authorized to make it happen Principal 6: Build in Integrity /Quality – perceived integrity and conceptual integrity – Making sure customers expectation are met – Key is early and often communication , feedback, testing
  8. 8. Principal 7: Optimize the whole – Sub-optimization: Tendency to solve problem by breaking system into parts and optimize each and individual part – Usually will be leading to “tragedy of the commons” – Look at the entire value stream – Continuously review product and process development.
  9. 9. Success story • BT Adastral, 50% sooner than expected. 80% ROI in the first year. • Timberline Software (now part of The Sage Group), estimates that improvements in quality, costs, and time to market were all greater than 25%
  10. 10. -On time delivery -Scrap reduction -Space utilization -Total project work reduce -Project rework reduce -Project costs reduce -Improve productivity - Success depend on discipline, commitment and technical skills - Role of a business analyst is crucial - Flexibility in requirement
  11. 11. Conclusion • Effective principals in terms of cost-related • Effective principals in terms of quality-related • Need a strong team work and discipline from all party involved including customer/client
