From experience we know that the implementation of new techniques and methods for the improvement of a software development process can not be done overnight.

We tend to underestimate the problems in connection with the implementation. That is because team members affected by the changes will need to learn new methods and techniques, which will then take more or less time depending on prior knowledge and affinity.

If you introduce too many radical changes at once you will run the risk of waiting before the teams will attain their former productivity. An atmosphere of uncertainty and unconfidence may rise before the benefits of the innovation even can become apparent.

Manageable innovations realized step by step in one or two pilot projects will bring about a sense of achievement, motivating the team to adopt more changes.

Thus a smooth realization of improvements, including training and vocational adjustment, is possible in the course of day-to-day business.
