Welcome to the not knowing ( we need to embrace uncertainty ) - Mike Cohn

In one scene of the TV show Mad Men, a young advertising copywriter (Peggy Olson) asks her boss (Don Draper) how to know which of her advertising ideas will work best.
He tells her she can’t know in advance, which frustrates her. He then adds that part of her job is “living in the not knowing.”

Part of our job, too, is living in the not knowing.

To survive--perhaps even thrive--here in the not knowing, we need to become comfortable with uncertainty. That means we can’t:
  • Know six months in advance exactly what will be delivered on what date and at what cost
  • Know exactly how much more productive one team is than another
  • Know how users will respond to a feature before they see it

Similarly, we can’t even really know things such as that velocity will go up when a good, new member is added to the team. It should, but it’s not guaranteed.
I can think of at least a couple of situations in which adding a good person to the team reduced velocity for more than the first few sprints while the team adjusted to the new member.
And, of course, we can’t know what external forces may affect our product, company or industry.

We are all living in the not knowing.

What can we do about it? As Kent Beck put in the subtitle of his book XP Explained, we need to embrace uncertainty. We can do that by:

  • Realizing that whatever uncertainties our organization faces are also faced by our competitors. To outdo your competition, you don’t need certainty. You just need to deal with uncertainty better than they do.
  • Not wasting needless time trying to eliminate uncertainty that cannot be eliminated. You could waste a lot of time striving for certainty. And living in the not-knowing, you’ll never reach it, so stop trying.
  • Acting on whatever information you already have or can get quickly and efficiently. In a world where we can’t know everything, the best recourse is to act on what we already know and then learn more by iterating on the product.
Welcome to the not knowing. The sooner you can get used to being here, the sooner you can succeed with agile,
Mike

PDCA & SCRUM (or Agile); Why is it important?

The PDCA (Plan DO Check Act) cycle was made popular by Dr. W. Edwards Deming. This is a scientific cyclic process which can be used to improve the process (or product). This is cyclic in nature and usually time boxed.

Plan 
This is the first stage of the process. During this step the team discusses the objectives, the process and the clear conditions of exit (conditions of acceptance). This stage sets the measurable and achievable goals for the team.

DO
Team works together to achieve the objective set in the planning phase. Team works with the set of agreed process.

Check
Once the implantation is done team regroups and verifies the output and compares it to the agreed conditions of acceptance decided during the planning phase. The deviation, if any, is noted down.

ACT
If any deviation in planned tasks is observed during the Check stage, a root cause analysis is conducted. Team brainstorms and identifies the changes required to prevent such deviations in future. Team also brainstorms idea…

SCRUM- Who should write a user story

Traditionally user stories (or requirements) were written by Business analysts. They used to prepare big documents after months of study. It was a herculean task. I used to get such UI/Functional specification documents. I have fixed a lot of bugs because I missed few text in such 1000 + pages document. This is not the only interesting part. Some of the requirements were so weird that I often wondered why I am creating the features which no one is going to use. If I had the option I would have recommended a better option. If the BA’s misunderstood some requirements & customers failed to correct those few words in the epic requirement then we will have a nice situation.
In the agile world the story is different. Product Owners are primarily responsible for user stories. But can anyone else also contribute? Yes. Definitely yes In actual environment many users write user stories. The first requirement may come from end user. The PO, tech architect, scrum master, BA’s... anyone can upd…

What are the rules of scrum?

A relatively new person to scrum asked me this question last day. My answer to that person was yes. But really does the scrum have any rules? Scrum is a framework which helps us in developing software. It has very few rules and apart from those basic rules rest of them are guidelines like best practices.

Some of the rules 

The roles of Scrum
•Scrum Master - http://www.theagileschool.com/2012/03/scrummasters-checklist-roles.html
•Product Owner
•Feature TeamThe PDCA cycle (http://www.theagileschool.com/2012/05/pdca-scrum-or-agile-why-is-it-important.html )  frequent communication about risks (daily)
•Plan – Sprint planning
•Do – Actual engineering sprint – deliver a potential shippable code
•Check – Sprint review
•Act – Retrospective 
The scrum guide @ http://www.scrum.org/Scrum-Guides will be a good guideline for teams/companies planning to start scrum. If you are following the recommendation in these then you are following scrum.
Apart from these rest of the ceremonies and artifacts are there…
