Systems Development Life Cycle (SDLC)


Right-sizing

There are many factors which can be used to help determine the size and complexity of a project. These include:

  • overall cost estimate
  • whether or not the data model or data schemas are required or must be changed
  • number of Business Areas involved or affected
  • extent of impact within those business areas
  • overall technical complexity
  • overall project Risk
  • number of interdependencies with other applications
  • whether there is planned innovation or whether the project follows existing standards
  • whether the project requires changes to policies or standards

The range of responses for these factors have been grouped into three general categories of projects: simple, intermediate and complex.

For any given project, depending on the category that the project falls into, there are different deliverables required. Some are mandatory and some are optional.

A Break-Fix Project represents a special case of the SDLC Rightsizing checklist for operational work which is needed to maintain support of current business by an existing production application.  This is not intended to cover any system related activity requiring more than 3 weeks work or an expenditure of more than $5k, nor is it intended for any Capital project, or system activity that has been authorized by a Business Case.

Steps to right-size your project:

  1. Use the right-sizing calculator to determine your project’s right-sizing category (Simple, Intermediate, Complex). There are 9 questions in the calculator. Fill in the header information and use the pull-downs beside each question (click on appropriate response cell) to answer the question for your project. Once you have answered the questions, the right-sizing category will appear at the bottom of the page. Save a copy of the file with your responses in your project folder for future reference and print out a copy for review/signoff with your Manager and Project Sponsor.
  2. Based on the right-sizing category, take a copy of the appropriate checklist for this category (4 checklists links: Break Fix, Simple, Intermediate, Complex) . If you disagree with any of the required deliverables (mandatories), then fill in a justification as to why the deliverable is not applicable to your project. For optional deliverables, review to confirm that they are truly optional. (If the deliverable is applicable to your project, it should be changed to required and a reason filled in.) Save a copy of your file in your project folder for future reference and print out a copy for review/signoff with your Manager and Project Sponsor.
  3. Review the Right-sizing calculator responses and Right-sizing checklist with your project sponsor and IMG Manager and get approval for your responses. Once you have received approval, this will form the basis upon which the planning and budgeting of a project should be based.

If project scope or other factors change during the course of the project, you may need to revisit the right-sizing and determine whether or not a change to the right-sizing category is appropriate. If so, this change should be managed through regular project management change control processes.

Note: For technology only projects, please complete the same steps above. The right-sizing checklists show which deliverables are not applicable for a technology only project.
