The OIT Systems Development Life Cycle (SDLC) is an important guideline to use when developing systems or implementing third-party solutions. In addition to helping implement more robust and secure systems for UCI, it also helps address future audits of IT systems by providing the procedures and documentation required to meet the expectations of the auditors.

The SDLC described here is meant to provide a flexible set of guidelines that can be adapted to any project by tailoring the steps, processes, and procedures to meet specific needs of a project. For more information, see Tailoring the SDLC. An overview diagram of the entire process can be downloaded in PDF or Microsoft Visio 2010 format.

Agifall vs Scrum

Both Agifall and Scrum are widely used methodologies for different reasons.  Although most projects adopt one methodology over the other, the non-traditional hybrid method of using parts of each methodology can also be effective in arriving at the desired project outcome.  Detailed information on each methodology tailored for OIT can be found in the following links.

Consider Agifall if: 

  • The team has done similar projects before and scope of work is known in advance
  • Except for reviews, approvals, status meetings, etc., a business user presence is not strictly required after the requirements phase.  Meetings can still occur on an "as needed" basis.
  • Priority shifts can still occur and change impact is acceptable in terms of scope/budget/timeline.
  • You’re working with fixed-price / fixed-bid contracts

Consider Scrum if:

  • Project has a high degree of uniqueness (high risk) or requires considerable R&D. The final product may not be fully defined and the details can unfold iteratively over multiple sprints
  • Business users involvement is recommended at the daily scrum and user has early opportunity to see delivery.
  • Priority shifts can occur during mid-sprint and change impact is acceptable in terms of scope/budget/timeline.
  • You’re working with time/material contracts.
  • You want the option of closing a project early once sufficient value is created (avoiding "everything but the kitchen sink" pitfall)
  • No labels
