Dear Mr.Rajeev,
First let me explain the question itself and answer in that context.
Ratio-Trend Analysis
The basic principle here is to say if it takes six people for example, to perform amn existing amount of work, it will take twelve people to do twice as much. Organization measure activity levels in a variety of different ways. The ratio between direct and indirect in manufacturing is classic one.
Individual departments in an organization also will have their own rule-of-the-thumb measures. A sales department, for instance, may have an idea of the number of customer calls a sales person should make in a week, and indeed, use this as one criterion for monitoring sales efficiency. If business plan projects an increase in the number of new customers, this can be translated into proportionate increase in the sales force.
The problem with measures like these is that they are crude. They take no account of economics neither of scales which affect efficiency nor of local conditions; nor of the potential of new methods and technology to increase efficiency.
For detail transfer of know how, I charge consultation fees depending on deliverables and technical evaluation of projects.
