Resource planning

[Mike Pokraka]

Hello Ramanan, 

 

That's a pretty major project, and there is a good reason all projects go
through a planning phase. Faced with the same question I would estimate at
least a month's work to come up with an answer that's anywhere near
realistic. 

 

For starters there are many factors beyond workflow that will influence your
requirements, such as size and makeup of the overall project team, length of
project, willingness to invest in the right skills. Are you going to employ
4+ years' experienced consultants, or find ABAPers who have built the
occasional WF, or train up inhouse staff? 

 

Next you have the workflows themselves. I've built approval workflows taking
from two days to over a year. Even specific workflow scenarios are no
measure: an invoice approval can take 10 days at one client and 5 months at
another (also based on personal experience). 

 

You ask how many administrators? What sort of total volumes do you expect?
(You obviously need to volume estimates of each of the workflows..). Do you
use HR? More experienced resources building the WFs will pay off in reduced
maintenance. The workflow I mentioned above created jobs for two
administrators - just looking after the one WF.

 

Based on the info in your question, I would seriously suggest you engage an
Experienced (with a capital 'E') consultant for at least a few days to get
you started on answering it. 

 

If you insist on a guess: 50% chance you need between 5 and 10 people, 50%
chance you need more or less than that. Flip a coin to see which one. 

 

Cheers, 

Mike

Dear WUG,
There are 100 workflows expected to be up and running in ECC6.0
Please consider that it is not know exactly what are the workflows now.
But please consider that workflows will be used for create and maintain of
all major master data objects and pretty much for regular task distributions
like PO release, invoice processing etc.,
 
My questions are:
 
How many personnels are required at the Development phase for these 100
workflows?
 
How may personnels are required for 'maintain' and 'administer' the
workflows? 
 
Anyone who worked at this level, please I value your inputs very much.
Please respond with your experiences and emprical calculations.
 
thanks in advance.
Ramanan
