Agile will fail at my workplace because of ...

• The concept of dedicating to one task at a time is not supported

• Because of our culture

• They won’t change

• Of me

• It’s counterintuitive and hard to practice

• Too focused on mechanics

• Ridiculous product owners

• What we do already works

• Not everyone on our team understands it

• We only fund capital projects

• My boss who manages with fear

Figure 2. Implementation steps to develop a large computer program for delivery to a customer.

I believe in this concept, but the implementation described above is risky and invites failure. The problem is illustrated in Figure 4. The testing phase which occurs at the end of the development cycle is the first event for which timing, storage, input /output transfers, etc., are experienced as distinguished from analyzed. These phenomena are not precisely analyzable. They are not the solutions to the standard partial differential equations of mathematical physics for instance. Yet if these phenomena fail to satisfy the various external constraints, then invariably a major redesign is required. A simple octal patch or redo of some isolated code wil l not f ix these kinds of diff iculties. The required design changes are l ikely to be so disruptive that the software requirements upon which the design is based and which provides the rationale for everything are violated. Either the requirements must be modif ied, or a substantial change in the design is required. In effect the development process has returned to the origin and one can expect up to a lO0-percent overrun in schedule and/or costs.

One might note that there has been a skipping-over of the analysis and code phases. One cannot, of course, produce software wi thout these steps, but generally these phases are managed wi th relative ease and have l i tt le impact on requirements, design, and testing. In my experience there are whole departments consumed with the analysis of orbi t mechanics, spacecraft att i tude determination, mathematical opt imizat ion of payload activity and so forth, but when these departments have completed their di f f icul t and complex work, the resultant program steps involvea few lines of serial arithmetic code. If in the execution of their d i f f icul t and complex work the analysts have made a mistake, the correction is invariably implemented by a minor change in the code with no disruptive feedback into the other development bases.

However, I believe the illustrated approach to be fundamental ly sound. The remainder of this discussion presents five addit ional features that must be added to this basic approach to eliminate most of the development risks.

... is like carrying one of these

Page 10: Being agile while standing in a waterfall

Story time!

Wednesday, 23 October, 13

Page 11: Being agile while standing in a waterfall

Once upon a time ...

• Final component of a larger program

• Estimated at 1200 days

• Drop dead date of 3.5 months

• Highly visible if we failed

• Core team assigned of 5 IT people

• Waterfall was all we knew

Wednesday, 23 October, 13

Page 12: Being agile while standing in a waterfall

Go!

• 15 contractors in the door within 2 weeks

• Secured a team room

• Broke the work out into projects

• Developed a mantra: “Failure is not an option”

• Strong executive sponsorship

Wednesday, 23 October, 13

Page 13: Being agile while standing in a waterfall

The Result!

• Delivered on the date we said we would

• Actuals came in $8000 under budget

• Delivered all key scope items

• No significant quality issues after go-live

• Happy customer!

Wednesday, 23 October, 13

Page 14: Being agile while standing in a waterfall

Another story!

Wednesday, 23 October, 13

Page 15: Being agile while standing in a waterfall

The situation

• Towards end of a larger troubled project (we kept dropping scope)

• Team only available for 3 more months

• Budget defined by available people and time

• Low key enhancement project

• Waterfall was best described as a religion

Wednesday, 23 October, 13

Page 16: Being agile while standing in a waterfall

Go!

• Secured a war ‘area’

• Given free reign to ‘try something different’

• Simple one sentence scope statement

• No authority to NOT do something in the department’s process

• Executive sponsorship watched closely

Wednesday, 23 October, 13

Page 17: Being agile while standing in a waterfall

The Result!

• Finished early

• Finished slightly under budget

• Features delivered exceeded customer expectation

• No quality issues after go-live

• Happy customer!

Start with theAgile Manifesto

We are uncovering better ways of developingsoftware by doing it and helping others do it.Through this work we have come to value:

Individuals and interactions over processes and toolsWorking software over comprehensive documentation

Customer collaboration over contract negotiationResponding to change over following a plan

That is, while there is value in the items onthe right, we value the items on the left more.

Why do we need Change Management?

Decisions are made prematurely!

Our customers cannot possibly know what they want in detail at the start of a project

What can you do about change?

Embrace it!Welcome changing requirements, even late in

development. Agile processes harness change for the customer's competitive advantage.

Things I’ve learned

• Culture cannot be changed - change how the work is done and culture will follow

• Start from where you are today and never be satisfied

• Improve the whole

• Improve one step at a time

• Iterate (Build Measure Learn)

• Have fun!
