Systems Development Summary

Using a checklist as shown in Exhibit 1 can help to get things started. The point is that basic documentation imposes order on every development effort. Increased order allows for more thorough and consistent management of development processes. More thorough and consistent management results in more realistic schedules and staffing for future development work, whether it is new application development, legacy system conversions, maintenance work, or additional types of documentation for the marketplace.

Establishing a practice of basic documentation provides ancillary benefits in that contract employees can be brought up to speed faster and their work can be checked and managed better. New technology can be adopted into environments more readily. Short- and long-term planning and bids for funding can be developed more meaningfully and documented more completely. In all, just sticking with the basics creates a win-win situation for everyone from management, to developers, to users.
