Do not build if you can buy existing software products.
A national experience in acquiring software for ITS projects.
- Do not build new, customized software if an off-the-shelf suits your needs. Customized software costs more and adds risk to a system.
- Maintain the flexibility to relax requirements to purchase a system that provides the best fit. This requires being able to live with the recognition that an off-the-shelf solution probably won’t match your vision of the ideal solution. An off-the-shelf product may not do everything on your wish list, but an 80 percent solution may be good enough. The off-the-shelf theme is one that the private sector particularly endorses. If system requirements have been identified that preclude off-the-shelf solutions, then they should be thought through and determined how important those requirements are and at what cost.
