Tactical Management is a dynamic process that needs to provide flexibility of the organisation in the decision making. This being said, in the organisational environment, it is my believe that Tactical management needs to especially focus on the portfolio and the programs, where organisational values, decisions, results and delivery are placed. According to PMBOK resources, this segment of portfolio and programs is related to the portfolio review and strategy and it is of crucial importance for the entire organisational environment. This is the segment that proves tactical management to be larger in the terms of scope vs. the project management, but it also points out project management as an essential segment in every organisation.
