Unit Development and Review

This is the part that developers prefer. Here the developer or team of developers will hand code the solution as per the SDS requirement document.

The process must be reviewed against the SDS all the way through the development process. Failure to do so will result in a poor product and possibly cost the development company to fix any pending problems.

Unit development can use a variety of Rapid Application Development (RAD) applications. If the SRS has requested certain development tools be used then these tools and methods must be used. Maintenance is more than likely going to be done by the purchaser and not the supplier.

If a developer sees a problem with the design then they must regress and seek clarification from their superiors and/or the client. If a problem is found here then it may result in extra costs for the client. The client may choose to ignore the problem or the provider may choose to swallow the extra costs.
