Duration of workflow projects

[Stefan Altendorfer]

Hi all,
 
We are going to lead a project which has to implement a SAP Workflow based
purchase requisition and invoice approval scenario. We will have a max. 5
level approval scenario for purchase requisistions and a 2 level approval
scenario for invoices and all employees (2000) will be users in SAP and in
the workflow. We already have done the first Business Blueprint (showing
alternatives and solutions) and we now have to tell the customer if their
new goal to implement the whole workflow within 2 months is possible or not
(I doubt it).
 
For this project we were given only one Workflow engineer (which
unfortunately has no ABAP Knowledge) and if we have big luck there will be
an additional one with more experience and ABAP knowledge, otherwise I will
have to do the ABAP part. We will implement this solution on a 4.6B System
and we'll use MS Outlook instead of the SAP Inbox.
 
>From your experience, can someone tell me how long an implementation of a
standard workflow scenario approximately will take? I have heard times
around 13 Months which in my humble oppinion is very long, but I am not a
SAP workflow specialist at all (normaly working with CORBA, COM, XML and
SAP).
 
Thanks,
 
Stefan Altendorfer
