80:20 RULE“DSDM assumes that 80% of the solution can be developed in 20% of the time that it would take to produce the total solution. DSDM focuses on this 80%, leaving another 20% for later revisions” (Clifton, 2003).• Must haves A review system to allow staff members and volunteers to oversee the programme. I would like to be able to extract reports on attendance, group performance, the application of funds, etc. I would like to be able to extract a map or calendar, showing the weekly schedules and work assignments, that I can print out and stick to the notice board. I want to be able to send messages to people and log all communication between us. This can serve as a running record of communication. The system needs to be able to track various projects at different branches. The system needs to be able to provide reporting on all projects at a particular branch.• Should haves We should be able to define search criteria over all records. For example, a search for “violence” should return a list of all youths who have the word “violence” listed on their records. The system needs to track what branch a particular youth is registered with. We should also be able to change this, should a person move to a different location.• Could haves This system should be the basis for the new, company-wide system and should be highly extendable. • Won’t haves (would like to haves but notthis time…) The system should also be personalisable. For example, if I want a facility that someone else doesn’t want, I should be able to commission it and use it, like a browser plug-in.
