We have been using our tracking system more and more to manage our work. This uses an online form to request fixes/changes to the website, and as we work on it the ‘ticket’ is updated and finally closed by the client.
We just released a complex ecommerce site for user testing, and we gave the end user access to the tracking site. This meant that changes went directly from the tester to the developer, bypassing the agency project manager. It significantly reduced the load on the project manager, without losing control. In fact the development was much more under control than earlier projects.
We have another client who we do time and materials maintenance. Every month they now get an invoice with a list of tickets closed (by them) that month, and timings to the nearest minute for each. It makes it very hard for them to argue with the billing. It also gives them control over their budget as they have access to a real-time cost analysis during the month.
Now, at the suggestion of a partner, we are using the system to control all quotes. Each quote is a ticket with the brief and every version of our proposal attached. It keeps a record which we all have access to.
