Estimating workflow hours

Tue Mar 22 08:24:09 EST 2005

I am sure SAP has some sort of measuring stick when selling the product
line. 
So there must be some SAP guidelines on development hours. *hint* 

We estimate the best we can. I am just looking for some sort of
supporting documentation 
as a back up.

The good old "how much time do you feel it should take" method is in
use
here. No formal methods.

Not that we are making many new workflows, but estimating is one of
the
least mature areas of software development whether it is workflow or
traditional coding. I used to work with software measurement and
estimates
for a previous employer, and even when using formal methods with
experience
data it is very difficult to make estimates. Unlike many other
industries
we "never" make the same product twice, and often it is not the same
people
working together except within a project. So all we have to help us
when
estimating is previous personal experience, unless you have been
gathering
experience data using some formal method.
Assuming you have a near perfect specification you can probably make a
very
reliable estimate, at least if you have some previous experience data.
So
one trick is of course to say the estimate assumes there will be no
changes
in or additions to the specifications. That should give you a safe
escape :
-)

Not much help I guess.... you are on your own. My best advice: always
give
the estimate as a range. When there is high uncertainty an estimate of
1000
hours doesn't say as much as between 500 and 3000 hours. The second
best
option is to give an estimate and a quantified uncertainty. However, in
the
latter case the project manager will most likely forget the uncertainty
and
use the estimate.

Ask the accountant for an estimate on specifying and verifying the
controlling processes required to be compliant with the
Sarbannes-Oxley
act.
Can't do it? Well...

I am looking for some rough guidelines for estimating cost of WF
development.
Not an exact science I know but some general guidelines on what others
are
estimating on development would help.

Would be nice to estimate by days, weeks, and months but project
management and
accountants don't like that method.

Any help is appreciated.
