From Nothing, to Agile
Engineering methodsplan-driven methodologies
Predictive? Process oriented
Document oriented
Agile methods test-driven methodologies
Adaptive! People-oriented
Code-oriented

Predictive Vs. AdaptiveSeparation of Design & Construction
Design: difficult to predictexpensive & creative people
Construction: easier to predict
![Page 8: CSCW2015 review](https://reader034.fdocuments.in/reader034/viewer/2022042819/55cde509bb61eb7f3b8b4663/html5/thumbnails/8.jpg)
Predictive Vs. Adaptive
CrucialQUESTION !
Can you get a design: 1 that is capable of turning the coding into a predictable construction activity?
2 If so, is cost of doing this sufficiently small to make this approach worthwhile?
look very good on paper,yet be seriously flawed when you actually have to program the project
![Page 9: CSCW2015 review](https://reader034.fdocuments.in/reader034/viewer/2022042819/55cde509bb61eb7f3b8b4663/html5/thumbnails/9.jpg)
False Conclusion on Engineering Jack Reeves: “anything that you can treat as construction can and should be automated.”
● In software: construction is so cheap as to be free● In software: all the effort is design, and thus requires creative and
talented people ● Creative processes are not easily planned, and so predictability may
well be an impossible target.● be very wary of the traditional engineering metaphor for building
software. It's a different kind of activity and requires a different process

Unpredictability of Requirements
Requirements, are always Changing !● understanding the requirement is though● software dev is a design activity● basic materials keep changing rapidly ● difficult to see value of a feature until use for real● no stable requirements = no predictable plan
Question: what we do about it ?
![Page 11: CSCW2015 review](https://reader034.fdocuments.in/reader034/viewer/2022042819/55cde509bb61eb7f3b8b4663/html5/thumbnails/11.jpg)
Misunderstanding Requirements
leads to people using a methodology in the wrong circumstances, such as:
using a predictable methodology in an unpredictable situation
![Page 12: CSCW2015 review](https://reader034.fdocuments.in/reader034/viewer/2022042819/55cde509bb61eb7f3b8b4663/html5/thumbnails/12.jpg)
What to Do? a process that can give you control over an unpredictability.
Adaptivity
![Page 13: CSCW2015 review](https://reader034.fdocuments.in/reader034/viewer/2022042819/55cde509bb61eb7f3b8b4663/html5/thumbnails/13.jpg)
Control Unpredictable Process
Adaptivity with iterations
TEST !
Why tests? 1 bugs 2 misunderstood requirements
![Page 14: CSCW2015 review](https://reader034.fdocuments.in/reader034/viewer/2022042819/55cde509bb61eb7f3b8b4663/html5/thumbnails/14.jpg)
Control Unpredictable Process
Key question:
How long the iteration should be ?
Depending on each agile method
adaptivity with iterations
TEST !
Why tests? 1 bugs 2 misunderstood requirements

With Adaptive Customer Agile approach:fix time, fix money, vary scope
1 constant reworking of plan 2 risk control 3 a late change in requirement: competitive advantage
![Page 16: CSCW2015 review](https://reader034.fdocuments.in/reader034/viewer/2022042819/55cde509bb61eb7f3b8b4663/html5/thumbnails/16.jpg)
With Adaptive Customer Business success?
On-time? on-cost?(predictive methods)Business Value ! (Agile methods)
The customer get the software with more value than the cost

Putting people first synergy: adaptivity require a strong teammost good developers prefer an adaptive process

Putting people first plug-compatible programming units Engineering
● Frederick Taylor's Scientific Management approach.
● “Achilles heel” of measurement based management.
● leads to high levels of measurement dysfunction.
responsible professionals Agile
● accepting the process rather than imposition of a process
● developers make all technical decisions
+ Business Leadership

Self-Adaptive Processeach iteration:
What did we do well?What have we learned? What can we do better?What puzzles us?
leads to ideas to change for the next iteration

Flavors of Agile Development
1 2 3
4 5 6
Extreme ProgrammingCommunication, Feedback, Simplicity, Courage, Respect14 principles, 24 practice
Scrum
sprintsdaily scrum meetings
Crystal family of methods
safety (in project outcome), efficiency, habitability (developers can live with crystal)
Context Driven Testing
questioning mainstream testing thinking
Lean Development
overlaps & inspirations between lean production and software development
Unified Process
a process framework Use Case Driven problem: its infinite variability

Go Agile? NOT for everyone, BUT could be used by moreTo start with:
1 suitable projects to try agile team & customer want to work with it project more critical than comfortable with
2 find a mentor experienced in agile3 follow their advice try methods first
4 hard to tell where the boundaryWHERE NOT to use? never impose on a team who doesn’t want it
