Two Guys Arguing

When IS the last responsible moment?

XKCD: Responsible Behavior

XKCD: Responsible Behavior

As agile software developers we work hard to make the development process as flexible  and lean as possible for our customers.  We work hard to estimate accurately, deliver working code quickly, and only do the work needed to finish the story right in front of us.  This discipline is hard but keeps our customers in the loop and getting the most for their money/time.  In order to keep up with the customer’s every changing requirements we often push-off decisions to the last responsible moment.  By delaying making expensive decisions until our hand is forced, we reduce waste and can stay focused on delivering value with each finished story.

But, when is the last responsible moment?  Who decides?  Has it changed?

With our heads down in the trenches, knocking out stories left and right, and moving fast toward our client’s vision … we have to keep these questions in mind.  A recent project reminded me of this.  Our team did a great job at empowering our client to shift our priorities as their business understanding changed.  We offered options, gave accurate estimates for stories, and allowed them to shift the work at hand each iteration.  We did exactly what we were setting out to do.

Unfortunately, we were so focused on short-term flexibility and options that the higher level vision began to slip, and some decisions were made AFTER the last responsible moment.

The key here is the responsible.  While we work to increase our productivity, reduce waste, and keep our customer’s immediate desires met … we need to keep in mind that the short-term decisions add up.  Long off decisions and high level visions don’t need to be fully spec’ed and decided day 1, but the same way we maintain our suite of tests as requirements change, short-term decisions needed to be reconciled with the high level vision.  A great team keeps in mind when this last responsible moment is for different kinds of decisions and revisits these frequently.

Stand up sit down fight fight fight

Prompted by a question from my good friend Kevin Berridge about agile team stand-up meetings, I quickly came up with a long list of do’s and don’ts but nothing substantial.  Nothing immediately profound.  Any quick google search can give you tips, tricks and pitfalls.  I wanted something more.  To try and ignite my thoughts I began writing down words that came to mind when I thought about a good daily standup meeting …

Wordle: daily stand up meetings

When daily standups go well, the team has a clear understanding of how they go to where they are today, where they are trying to go, and the route they are going to follow.

When daily standups go bad, individuals get frustrated, time is wasted, problems reoccur, and the meeting ends up being a means to justify paychecks and appease management.

Whether you focus your meeting on what each individual did yesterday/is doing today/is blocked by or on how the story board changed from yesterday, the real goal should be focusing the team toward a common short term goal, and making any impediments very visible. The meeting should be for the team, by the team and to the team.

Often I see standups where everyone ends up telling the PM/Scrum Master/Team Lead what they worked on yesterday and an excuse about not yet knowing what they were going to do today.  Have the team talk to the team.  If what you are sharing doesn’t have value to the rest of the team, don’t share it right now.  If a detailed discussion starts between on some members of the team, wait until the standup is over.  If the meeting stops providing value at 5 minutes, stop the meeting.  If the meeting is going past 10-15 minutes, stop and have the team decide if it should continue or be broken up in favor of smaller discussions.

Daily standups are great way to get everyone on the same page, re-focus the team on the highest priority items, and lay out a quick plan of attack.  Like time-outs in the middle of a big game, they need to help bring everyone together and formulate a short term plan to victory.  Especially when King James shows up.

Agile Underwear Gnomes

Agile is all about the profit

While considering my teammate Amos’ recent blog post where he debates what Agile really is my mind was drawn to a statement our current client made during one of our early project kickoff meeting.  While discussion why his clients have been successful following his plans he made the statement:

You will never go broke, making a profit

At the time this seemed like a good joke and litte more.  However, the more I thought about it, the more it rang true.  What does this have to do with Agile software development?  While questioning what is or is-not Agile and what his definition of Agile might be missing, he says:

… The one thing that I didn’t mention above. … Delivering a useable project at any point in development. That is it. That is what I’m missing. This has got to be the hardest part of agile. …

I think the key here is the value of a shipped product is ALWAYS greater than that of one sitting on the shelf.  Value is the key.  To me, the agile mindshift is one of always producing value for the customer, for the team, or for yourself.

Produce value for the client:

  • by adapting to their ever changing business needs with understanding, speed, and energy
  • by aligning all user stories with tangible user value and goals
  • by planning and documenting in inverse proportion to the item’s priority and deadline
    • worry about what is in front of you first and put off decisions to the last responsible moment (stolen and probably butchered from a WWBBD: What Would Brian Button Do)
  • by working on the highest bang-for-the-buck stories first, top down, and delivering working code as often as possible

Produce value for the team:

  • by conducting frequent retrospectives where the team can think about how they are doing and how they can be better
  • by realizing that many/most of a team’s problems are really “people” issues masquerading as technical ones
  • by actively paying down technical debt
  • by reducing knowledge silos and keeping the team only full of valuable members and all members valuable

Produce value for your self:

  • by staying motivated and positive
  • by keeping the thirst for knowledge alive and always learning from any experience
  • by taking greater pride in the success of the team over the success of an individual ego
  • by working to be a great communicator: to team members, to the client, to your code (Tests)

I didn’t mean for this post to turn into a list of things to do … but often our practices are the best way we can take abstract principles and make them tangible.  So long as the practices don’t become to focal point, they are a useful way to monitor, enforce and discuss the important concepts.

Profit really is the key.  Our client helped his clients by making sure they were profitable.  Sure, maybe they could have been more profitable, if they had taken bigger risks and bet the farm for instance, but year after year a steady profit is inspiring.

Which brings me to the Underwear Gnomes of South Park.  Their business plan was a simple one.

  1. Collect Underpants
  2. Profit

By focussing on providing value (profit) at each point along the way, maybe step 2 wouldn’t be such a mystery.  Granted, gnomes are pretty agile to begin with.  Fast too.
