Could you give me own examples on contemporary management theory?

Contingency Theory – often recognized as management by exception, contingency theory operates on the recognition that contingencies or exceptions occur, and rather than manage by those activities that are going "right", manage the exceptions, which we generally believe should be fewer. This grants more empowerment to the employees and allows management to focus on the areas that truly need improvement. It also provides for a means of contending with catastrophic events such as fires and 9/11. This theory become more prevalent in the aftermath of the 9/11 events as much of what occured in the days following was contingent management.

Systems Theory – the theory that everything interrelates, and that many things affect the problem. In saying that, when you look at a problem, you need to look at all of the influencing factors, rather that excluding things automatically because they seem like they fall outside of the root cause. Simply put, there is no one root cause, but many things that influence the end result.

Total Quality Management (TQM) – TQM is the management of the total quality of the output. That means looking at the entire supply chain and managing the quality of all of the inputs, from the initial supplier, all the way through the entire process of creating the output (product or service). Often, TQM focuses on quantitative metrics for measuring performance, and may use such methodologies as Six Sigma to quantify the effects of changes made to the process.
