Different BA Models
No Business Analyst (BA).
One BA.
Two BA’s.
Business Analyst working just for the Business
Unit
Second BA works for the IT group
In my experience, Either no BA or one BA
is the most common model.
Main Concepts
From the business point of view, they start with
working processes and need to end with working
processes.
IT projects improve processes or add new capability.
The absolute bottom line (no benefit but no loss).
“Do no harm first”
Document in the “Business” language
Must have at least *one* way that works for
each process.
Business Documentation
Before IT work, the Business Units need to document
(“As-Is” process mapping):
“Garbage In, Garbage out”
Processes
Inputs and outputs
In scope and Out of scope
Fix business process first (Six Sigma or Lean)
Quantify what needs to be improved.
Review various ways to improve the situation to balance cost
versus return.
Someone else’s statement: “If you automate a bad
process, you now have a more expensive bad process.”
Business Documentation
Process model benefits
Communicate to IT needed inputs, data modifications
and data outputs.
Standardizes business process before IT changes the
system and the business process.
Documentation is now in the “business” language,
allowing the various non-IT personnel to understand
where we are (“As-Is”) and where we want to go to
(“To-Be”).
Levels of Documentation
Deliverables:
SIPOC (Top level and Strategic level)
Process Maps (Tactical level but may include additional levels)
Requirements Template (to note locations or examples of process
inputs and outputs for reference)
Wish List Template (parking place for ideas of what the Business Unit
would like to explore).
Glossary Document – Describe the terms used in these documents so IT
people can understand what is meant.
Part of initial IT intake process.
IT designers also need the designs and specifications of any current
systems in use that may be interfaced to, updated or shut down.

As-Is process validation.
Test the documents: “Conference Room Piloting” (source unknown)
Use completed documents to “run through” documentation.
Make sure documents cover 100% of process map paths.
Include worse case or all known unique situations.
May also use random sample.
Testing done in conference room with process maps and business
documentation. Each person has their part of the map they normally
due day-to-day.
Physically write on the process maps showing the start through to the
end (input to output).
Run through each scenario and see if the maps truly show how that
situation would work:
Do I have the right information to start with?
Does the process allow me to do all the changes I need to?
Does the process generate the right output for the next steps?
Input documents for IT Design can have the highest cost to fix if
found in System Testing. Test the documentation first.
Process Change Freeze
Stop process changes when possible during IT
project.
If changes must be made, update As-Is
documentation and check on IT impact.
In case of major process changes during Design,
re-do the Conference Room Pilots.
Targets do move in an IT project. We must
adjust our aim to compensate.
Communication with the Business is critical. You
can’t design for process changes you don’t know
about.
Documents created during design phase
“To-Be” documentation. How work is done after
Go-Live:
The As-Is documentation is copied and now called the
To-Be documentation.
Normally the Top Level and Strategic SIPOCs do not
change in an IT project.
The process maps must show how the process will
change.
To-Be Requirements are normal IT requirements but
start from the As-Is Requirements. Everything from
the As-Is documentation must have a home or
explanation on the To-Be documents.
IT may also add in requirements from current IT
systems that the new system will now provide.
Design Validation
Once the design is completed and verified, it’s
time to bring the new To-Be process models
back to the Business for validation testing.
Use a “Conference Room Pilot” and same test
cases from As-Is testing plus random samples.
Check out test cases and other parts of the
testing plan during conference room testing.
The Business stakeholders must understand that
this is their final check before the major costs of
coding and testing starts. Process defects or
requirement defects after this point start getting
very expensive.
Final approvals for the To-Be documents
There must be some point where changes are
locked down so the project can actually end.
With the To-Be process maps and requirements, we
have management sign-off that this is what they want
and agree to. If there are any changes after
agreement, the responsible Steering Committee will
need to approve the change.
With agreed-to process maps and requirements,
Development and Testing can begin their work in
earnest.
Once all of the work is nearly completion, then we
start the final phase which is User Acceptance Testing
(UAT).
User Acceptance Testing
At this point, this is where we must demonstrate that
every input, process map and output is able to be
delivered by the new system:
Tests must prove one good way to perform all business functions.
Great time to show the comparison of old screens and old reports to
their new replacements.
Excellent time to check all training materials.
From a Human-Computer Interface stance, have system users outside
of the development team take the training materials and see if they can
figure out how to do the new process.
This is the last point the Business Units have to determine if the new
processes will work and/or complete for all processes.
Go-Live process and beyond
Rename To-Be documentation as As-Is.
Make sure process is in place to maintain process documentation.
Review process documents quarterly for changes (both business and
software).
Update all process maps before changes are made to any system.
To maintain maps and UAT tests
Have business teams use these documents as their SOP.
Best way to keep documentation current and useful.
Greatly reduced time & cost to fix systems.
Recent project
In this recent project I’ll call “Project X”,
here is key factors:
Purchased system from vendor that is customizable.
Involved multiple departments.
Included several regulated activities with stakeholders
both inside and outside of the corporation.
Drivers were high quality and cost containment.
Current systems were in place to allow time to
complete the project.
Project X
As-Is side of Project X:
As-Is process took around 10 calendar weeks.
127 existing processes were reviewed.
39 processes were marked out of scope.
87 current process maps were reviewed with
needed improvements listed.
4 Top Level SIPOCs were created and 23
Strategic SIPOCs.
55 new process maps were created or
updated from existing maps.
52 requirement documents and 8 wish lists
were also created.
Project X
Key factors in this project:
This process was new to the team and was documented just
before using.
All the business users who created or updated the
documentation were not trained Business Analysts. They were
all trained in what was needed to be done, how to do it and how
to review it.
One BB / process mentor (me) was available to the project for
roughly 10 hours per week.
There was one Business Analyst on the project working roughly
20-40 hours to assist the teams on creating / updating their
documentation.
Project X
Key results:
Business teams had documentation to refer back to as needed
during process.
Vendor had process maps to use to help design process flows
within their system.
Team could map various vendor configuration documents to
process documents to keep everything updated.
System go-live was “successful with minimal issues”.
However, now we are doing a project to develop common
“terms” and a common “process”.
Project Y comparison
Request was made for financial control reports to help
current manual process.
Requirements were vague and process maps were not
completely business or technical.
Took 9 months to create reports, cost $500,000 and
reports were not usable.
Then created requirements in business language and
then created translation columns for IT.
Created report example business could understand and
added IT needed terms.
Reports should be re-done after an additional 6 months
and $300,000. If reports had been done on time and
correctly, could have found defects in code releases that
ended up costing several thousands of hours to manually
fix.
