The main goal of connecting project management and tactical management is to achieve greater adaptability of the organisation, especially needed in these times of constant changes and challenges.
In project management, the project charter formally authorises the existence of a project and provides the project manager with the authority to apply organisational resources to project activities.(PMBOK6) On the other hand, the tactical management application process is more through research. This function is based on the management's decision to apply this in the company work. We spot this critical point as a connection dot between the two concepts. Providing project management functions with additional research possibilities in order to get more relevant information in the decision making process, is of essential importance and an asset that tactical management as a function can provide.
