Why IT needs lean
        by
Improvement
Why would we need that?
Well…
What exists today ?
CMMi
Do our customers have fewer
 incidents for that reason?
No !
Why ?
Let’s have a look…
… a closer look
First
There is a customer
And the customer has some…
Requirements
That we transform into…
Specifications
Specifications are checked
    with the customer
The customer
specifies his
requirements
Back to writing
 specifications
Then, we have…
Development
Second check with the
     customer
The customer changes
opinion
(Time has passed since
the initial requirements)
Back to development
(Or was it a specification
      problem?)
With some luck, we should
     be able to start…
… The tests
But then…
We find bugs
Back to development
More tests
One day we will get to…
Pre-production
It’s now time for…
… a third check with the
        customer
Bugs are found with the real
           data
Back to development
Functional bugs are also
         found
Back to specs
Back to development
And more tests
Then back to pre-production
In the end, we should
        be …
In production!
Yes!
But then, we get…
Incidents!
That we know how to fix…
 (Choose the best one)
Restart a job
Restart a job
Add disk
Restart a job
Add disk
Add CPU
Restart a job
Add disk
Add CPU
Add _________
Then…
(the production is redelivered)
New incident!
Now it’s time for a…
Problem analysis!
That will allow us to find…
The good solution !
(back to development)
(tests)
(pre-production)
(in production)
The customer is still waiting…
Finally you realise that!
Now it’s time for …
The task force!
Problem analysis again!
(back to development)
(tests)
(pre-production)
(in production)
…
Déjà vu?
Not strange that…
Specification teams
Developers
Test teams
Pre-production teams
Production teams
Incident management teams
Problem management teams
… are   overloaded!
…
Be lean!
