A Systematic Approach to Developing
Fit-for-Purpose Excel Models

2. How much time do you spend
on creating Excel models?

3. Most people spend too much time
on perfecting their work.

4. Start EVERY Model
by answering 2 key questions.

5. What is the purpose of the model?
Oftentimes, the model will be simple and used only for
some quick analysis. A core data set, simple formulae
(e.g., VLOOKUP), and pivot tables might suffice.

6. Who is your client?
Consider both formatting and usability of the model depending on your
client. If it is for your own use (i.e., other people will not see it) or you are
asked to “come up with a number,” then nothing fancy is required.
If the output is to be formally handed over to an external client, then a
top-notch model is what you will want to go for.

…is intended for your own use. Nobody else will work
with the model.
The focus is on getting the analysis right. No bells and
whistles. But you might need to update the model in the
future, so apply modeling standards wherever possible.

16. Level 2
…is to be used by an internal client. Most consultants
know how to deal with Excel.
Accordingly, the focus here is not so much on ease of
use, but on being able to review and validate the
accuracy of the analysis.

particularly experienced using Excel.
Accordingly, make the model as easy to navigate as
possible by using consistent formatting, color-coding,
and annotations, and ensure that it is impossible to
break the model itself.
