Obtain clear understanding of what exact work each person in a certain position performs on a planned basis. Also, obtain information on typical unexpected activities they are asked to perform. Now, it is true that this becomes easy to measure when the groups in question conduct a measurable service or manufacture components which can easily be measured.
- Identify inefficiencies within the daily activities your current staff performs.
- Implement simple measures by which your current staff can increase their productivity by atleast 10- 15 %. Though this may seem like a very high number for a manufacturing or service division, this is easily do-able for most internal functions.
This will free up your resources and then you can make an informed decision as to- if you would like to utilize your existing staff to expand your current service offerings or meaningfully re-structure your organization in a way, which will allow you to move these resources to other parts of your organization (with of course appropriate guidance and training).
