A quick summary of our approach to software & website development. We follow the Agile Manifesto which means we place value on individuals & interactions (over processes & tools), working software (over comprehensive documentation), customer collaboration (over contract negotiations) and responding to change (over following a plan).

  • 3. THE JOURNEY - WATERFALLOriginal software development was mostly a“hack away until it works” effort.Waterfall was born of the desire to better manage complexprojects. Analyse Design Build Test Release Welcome to the 1970s!
  • 4. SLIPPERY RESULTSSoftware project failure* exceptionally high at 61%.The main reasons for failure include:• Incomplete or Changing Requirements• Lack of User Involvement or Bad Communication• Delivered Late or Over Budget.
  • 5. OLD REQUIREMENTSUsing Waterfall We Try To:• Capture Detail About Requirements All At Once Before We Start.• Often Performed Independently of Eventual Delivery Team.• Estimate Project Effort and Cost Off Requirements.• Restrict Change by Penalising For It (and we still fail!)
  • 7. A NEW WAYDuring the 1980s and 1990s approaches changed.The goal: to fix what was wrong with IT project delivery.The result: lots of new great ways to do project delivery.The problem: which one to use?!In 2001 a group came together in Utah and bought manydisciplines together and produced the Agile Manifesto.
  • 8. 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 toolsWorking 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.
  • 9. AGILE APPROACHUsing Agile We:• Start with a set of Stories in a Backlog.• Collaboratively prioritise and refine Stories for build.• Accept that requirements can and do change.• Work using defined periods of time (a Sprint).• Extract Tasks from Stories to complete in a Sprint.• Always have shippable software.

  • 15. SCRUM BOARD Where we track all the stories
  • 16. BURN DOWNWork is broken down into a forecasted number of sprints & allsprints are completed within a pre-determined timeframe (e.g. 2weeks). Stories are allocated to each sprint in order of priority &progress is mapped on a burn down.
