I need a project about History of Managerial Accounting.

You may cover it from a position of arguing for or against a topic, the evolution of a topic, how that topic is used within a industry (you would select a company within an industry to cover), or how to demonstrate the topic. For example:

Arguing for or against a topic: Question: Is ABC still a value-added exercise?

The evolution of a topic: The History of Managerial Accounting

How the topic is used in an industry: The use of liquidity ratio analysis: a comparison between Ford Motor Company and the Automotive Industry in general.

How to demonstrate the topic: Developing a capital budget for a particular capital asset: Decision-making through capital budget models.
