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).

THE JOURNEY - WATERFALL
Original software development was mostly a “hack away until it works” effort.
Waterfall was born of the desire to better manage complex projects.
Welcome to the 1970s!

SLIPPERY RESULTS
Software 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.
OLD REQUIREMENTS
Using 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!)
OLD REQUIREMENTS
A NEW WAY
During 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 many disciplines together and produced the Agile Manifesto.
AGILE MANIFESTO
We are uncovering better ways of developingsoftware 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 negotiationResponding to change over following a plan
That is, while there is value in the items onthe right, we value the items on the left more.
AGILE APPROACH
Using 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.

SCRUM BOARD
Where we track all the stories
BURN DOWN
Work is broken down into a forecasted number of sprints & all sprints are completed within a pre-determined timeframe (e.g. 2 weeks). Stories are allocated to each sprint in order of priority & progress is mapped on a burn down.
Are we Done?(that’s a Scrum joke)
