6 Joel On Software The Joel Test: 12 Steps to Better Code 1) Do you use source control? 2) Can you make a build in one step? 3) Do you make daily builds? 4) Do you have a bug database? 5) Do you fix bugs before writing new code? 6) Do you have an up-to-date schedule? 7) Do you have a spec? 8) Do programmers have quiet working conditions? 9) Do you use the best tools money can buy? 10) Do you have testers? 11) Do new candidates write code during their interview? 12) Do you do hallway usability testing? Joel Spolsky

7 Typical Release Cycle Requirements Planning & Scheduling Prototype Development Testing Early Adopter Pre-Production Installation Release

8 Development Process Define Prototype Develop Test Refine

9 Genesis of Features Enhancement Requests logged through Support Oracle Technology Network discussion forum Internal Projects Example: Data Loading / Conferences / Customer Meetings Strategic Direction from Management Carried from Previous Release Define Prototype Develop Test Refine
