Everyone has hanging projects - those that last for months or even years. It seems that everything is tested, but because of the age of years the TOR does not correspond to the models, the layout of the design, or just something new agreed (a year ago!). How to pass it?
In any case, it will be long and torturous, but there is a chance to spend less time and money: do grouping through the protocol.
How it works. Once the site is made and you have tested it again, you send the protocol of surrender to the customer with a request to fill in or sign an acceptance report. In the first case, within 1-2 working days after receipt of the completed act, check the comments (their availability and compliance with the TOR), then assess these changes and put in a plan of work (for example, we have a weekly planning - that is, everything that arrived before lunch on Friday, we will have time to put the next week).
Thus, the corrections are made grouped, the customer is motivated to give them all at once, not to check the site in one section, and programmers have less switching from project to project, that is, higher productivity.
