In order to meet these objectives, the SDLC has many specific requirements it must meet, including: being able to support projects and systems of various scopes and types, supporting all of the technical activities, supporting all of the management activities, being highly usable, and providing guidance on how to install it. The management activities include: setting priorities, defining objectives, project tracking and status reporting, change control, risk assessment, step wise commitment, cost/benefit analysis, user interaction, managing vendors, post implementation reviews, and quality assurance reviews.
