How many business cases a consultant can work on simultaneously ?

Hi Mihai:

In my experience as a consultant, three (3) cases work well simultaneously. I have done two large projects and one entrepreneurial project at a time. There is no rule on how many projects you can do. Only you know what your limits are and if you are serving your clients well. The goal is to go beyond the customer's expectations in your work with clients so you should not spread yourself to thin.

Hi Mihail,

I have worked on multiple business cases supporting business development, pre-sales, IT strategy, Business Blueprinting and Business Processes. I don't think we can arrive at a rule of thumb as such. This boils down to the level of details needed (and what part of them is easily available!!)

It depends more on the depth you need to go. e.g. for Process Re-engineering or IT Strategy it is mostly a considerably heavy exercise picking up data, look at changes, picking out benefits likely to accrue, calculate the expected investment timelines and RoI points. The data on needed for the such business cases needs time and effort to extract [removed] This becomes a fairly engrossing exercise leaving little time for multiple cases at a point of time. 

On the other hand, business cases for supporting pre-sales and business development activities are at a fairly high level with most data based on assumptions and commitments and hence it is relatively easy to work on multiple cases in one go.

I doubt if we can actually get a definite number. It can be one or many depending on the needs and bandwidth as long as we can do justice to the needs.
