Maintaining old software is tricky. Changes to core functions can cause unexpected problems in other parts of the system. It's safer to create new functions than to alter existing ones. Thorough testing is crucial, but complete coverage is impossible. Careful consideration is key.
Facing fixed-price software projects? An expert offers five strategies to manage risks and customer expectations regarding cost and scope. These suggestions address estimation, planning, and funding to improve project success.
