3. The Airlines ERP Case Study
• An international airlines company wanted to re-engineer their legacy ERP
system into a web based ERP system
• The project was awarded to an IT company
• The IT company followed Scrum and delivered the application on time
• As the potentially shippable product increments were being delivered the
end users kept inspecting the features and accepted them
• However, it was only in the end when the vendor said all features are
delivered, the end users realized that the new ERP doesn’t automatically
connect to central reservation systems (Amadeus and Galileo) and that
they have to use the native interfaces of CRS
• This resulted in an additional manual step, end users could not use native
interfaces and the new ERP system was scrapped - A PROJECT FAILURE
How could this failure have been averted?

18. DA through the Automotive case study lens
• An on-going engineering application in an automotive
company
• Follows scrum with 3-week sprints
• Customer complains about productivity of the team and
quality of the output

19. Root cause analysis – 5 why method
Bugs escape first test cycle (New bugs introduced in subsequent test cycles)
Productivity concern
Quality concern
Testing-fixing takes more time
Test cases coverage not adequate
Test cases are written for bug, not for corresponding requirement
Requirement traceability matrix doesn’t exist; bugs requirements test cases

20. Accelerate value delivery – Maintain
traceability

21. • And then

“Maintain
Traceabil
ity”

22. Visualising an existing project through DA

Refer to

complaints and
map them to

improve

Disciplined
Agile
• None among Scrum, Kanban and SAFe methods address the software engineering elements of software
projects.
• How to improve requirements elicitation / documentation, what are non functional requirements, what are good architectural and design
practices, how to ensure high quality in testing etc. are not touched.
• Disciplined Agile not only improves Scrum, Kanban and SAFe implementations, but also provides guidance for
improving software engineering practices in the areas of requirements, architecture, testing, deployment etc.
Why DA?

25. Shu Ha Ri of Agility
✤ Shu : Follow the example (learn)
✤ Ha : detach (break the limits)
✤ Ri : Be fluent (create, innovate)
You can leave the team alone for them to figure out everything only
if they are in the Ha or Ri phase
• Traditional processes pegs the practitioners counter productively to Shu phase
even when practitioners have matured to Ha or Ri phase
• Scrum and Kanban do not attend to the Shu phase
• DA provides the guidelines needed for the Shu phase and the flexibility
needed for Ha and Ri phases

31. Comparing DA with other methods
Challenge Scrum SAFe Kanban Disciplined Agile
Cost escalation
due to expanding
scope
No guidelines No guidelines No guidelines Explore scope options help
in better integration of
requirement engg practices
Predictability of
releases
Predictability a major
challenge when time
boxes don’t work
On demand release at
program level improves
predictability but
cadence within ART still
needs time box
Pull based
systems improve
predictability
Disciplined Agile uses
Kanban where pull based
systems are the best option
Business agility No guidelines Excellent guidelines Scarce guidelines DA Flex playbook –
improves upon even SAFe
Cost challenges
due to resource
underutilization
Suggests full stack
dev team, but that is
very costly and
infeasible at times
Same as scrum Pull based
system ensures
better flow and
utilization
DA leverages Kanban as an
option where resource
utilization is a challenge
Adoption Big bang Big bang Truly agile Truly agile
Anti fragile Low Low High Very high
