SAPMEINTThe idea of this Wiki is to provide an project overview. what can be found where etc.
But additionally to that we also provide some details about our development and the current status, that is not that easily accessible just via the tools like Jira and cPro.
We believe that quality is a key element for a successful product that satisfy the customers and their needs. Therefore take a view minutes and check the Quality first section in this Wiki, where we list all quality actions we planning and executing. For us development is not done, when coding is finished, but when quality is assured.
