Introduction
The final management function of control closes the loop that started with planning. While the term 'control' can have some unfortunate connotations, such as authoritarian styles of management, when used correctly 'control' is merely a tool for measuring performance against expectations. After all:
You can't manage what you don't measure.
Evaluation and control must be performed systematically and employees must be willing to act on results: do not waste energy defending yesterday. Defending yesterday uses up resources today starving us from tomorrow.
Refer again to Chapter 5 and take another look at Blanchard et al.'s (1987) idea of SMART objectives. In Chapter 5 we said evaluation and control involve establishing performance targets and comparing the actual results with those performance targets. Evaluation requires analysing any deviations from the established targets and implementing the necessary modifications to maintain the desired course. This suggests that effective evaluation and control require an efficient monitoring system that measures progress towards set goals and produces readable, timely reports so that modifications can be made.
In essence, the purpose is to closely monitor and evaluate performance to ensure that the selected strategies are working. In this subject we have examined how a manager can use and coordinate both physical and human resources. We have concentrated on the necessary functions and roles of management and introduced the role of a leader. We have also considered planning, strategic management and implementation. We now move to evaluation and control.
The most brilliantly conceived plans, even when supported by sound organising, staffing and decision making are likely to be achieved only if the organisation exercises an effective controlling function that monitors performance and keeps the organisation on target.
In this chapter we consider the control function and the issues involved in designing an effective control system. Your textbook covers this topic in detail. This should indicate the importance that the authors place on this function of management.
In this chapter we will concentrate on material covered in Chapter 16 of the textbook. You will note that there are three supplements (managerial control methods; operations management and management information systems) in the textbook. Whilst we will not concentrate on these areas, you should read them to get a general understanding of the points.
An aside
You have probably heard of Murphy's Law: If anything can go wrong, it will?
I like to take a more optimistic approach: For anything that may go wrong we are prepared.
