System Development Life Cycle Extension 

Project Delivery Framework logo

May 30, 2008

The System Development Life Cycle (SDLC) Extension provides guidance to systems development practitioners by including a consistent toolset for addressing requirements, design, testing, and implementation of systems and system components. This toolset contains tools and guidelines that are intended to be integrated with the Framework toolset when a system or system component must be built.

The SDLC Extension toolset may be used selectively by including only those tools appropriate for a particular project. Each tool may also be tailored for specific project needs.

Additional tools are usable versions of the tools found in the appendices of the associated tools and the checklists within the System Development Life Cycle Review Guidelines.
