Example of lack of governance

We are delivering a new service support where we are facing the same situation:

• We are doing a great job in number of tickets.
• We are enhancing the application with little details requested by the customer that is enabling them to spend less time when using the tool.
• We are not closing all the errors of the application, recurring errors are appearing.
• We are not taking into account some functionality changes are affecting other parts, provoking new tickets appear.
• There is not enough control of the scope of the application, even when we have a detailed functional analysis that helped us to close the project in a good way.
• The complexity of the application makes that the use of the detailed functional document is necessary to perform the changes: and this use is not happening.
• We are able to close 1000 tickets, but not the application with zero errors.

We are suffering a deep lack of governance. Reasons?

• Communications at product level are not done in the right way.
• There is a lack of change management process when a functionality is requested.
• When a new release of the application is deployed, the documents are not properly updated.
• Client expectations are so high and they are not being managed in the right way.

We have a lot of job to do here,
