Using Lego to capture raw data for Cycle Time and Process Cycle Efficiency

 

Background

I’m one of six technical coaches engaged by a large bank to support an initiative to improve software delivery performance. The IT department is an established agile software development shop that uses the SAFe framework with Scrum at the team level. They are seeking to achieve continuous delivery, improve software quality, establish a developer-friendly working environment, and foster a culture of continual improvement.

We want to be able to show the effects of changes the teams make in their working practices. Improving delivery performance involves changing the way people work; therefore, we need measurements that aren’t dependent on doing the work in any particular way. Three metrics from the Lean school of thought are helpful: Throughput, Cycle Time, and Process Cycle Efficiency (PCE).

Where are all the Agile success stories?

Daniel Mezick confronts the elephant in the “agile” room in his post, Deviation from the Norm: “If current approaches actually worked well, then by now, thousands of organizations would have reached a state of self-sustaining, “freestanding” agility. Clearly, that is not the case.”

Pondering the question, several possible reasons for this result (or lack of) occurred to me. These are speculative and based on my own experience and observations.

40% to 99% of your team’s effort is wasted (give or take a bit)

Recently I noticed a post on Twitter that referred to this article by Eric Barker. Barker, in turn, shares information he learned in a conversation with Po Bronson, an author (with Ashley Merryman) of Top Dog: The Science of Winning and Losing. Now, notwithstanding the word “science” in the title, this is a “pop science” book, not a science book. It’s based in part on the authors’ “research” (reading statistical studies and so forth) and in part on popular assumptions – what we might call “leprechauns” or “urban legends.”.

The article rubbed me the wrong way, so I’m going to indulge myself with a bit of a rant.

Relief valve for Product Owners

In a pressurized system that contains a liquid or gas, when the pressure is too high the system can rupture at its weakest point, causing a halt to operations, damage to the system and, possibly, leakage of dangerous materials into the environment. To protect against this, people install relief valves. The valves guard against excessive pressure and wrong-way flow. One type of relief valve vents into the atmosphere. It is used in applications that do not have hazardous liquids or gases. Another type can direct dangerous fluids to an alternate route, possibly collecting them in a reservoir of some sort, while protecting the system from damage.

In large organizations that use an "agile" process with a formal role similar to the Product Owner (PO) role defined in Scrum, a common problem is that the individuals assigned as POs are asked to work on more projects concurrently than they can handle with due diligence. Often, they are simply asked to add PO responsibilities to their existing workload. Thanks to the historical preoccupation with maximizing individual resource utilization in management "science," the PO’s existing workload usually does not provide any slack. In short, they are already too busy to begin with. Continue reading Relief valve for Product Owners

How does collaboration begin?

The question was posed in a discussion on LinkedIn. It received the following response:

Is the question "how does collaboration begin" or "how do specialists become generalists"? I assume the latter.

Um, well, that wasn’t the question. What’s the value in assuming a different question, because you’d prefer to answer the other question? After a number of comments extolling the virtues of the generalizing specialist, a person showed genuine interest in moving himself and his team in that direction. He want to get started. That’s a good thing.

Instead of helping him get started, however, people just reiterated the end state. Just do. Just be. Just blah blah blah. There’s a certain word in the question. It’s a little word; nothing ostentatious. But I think it’s kind of an important word. The word is begin. Continue reading How does collaboration begin?

Don’t do anything stupid on purpose

It’s a familiar adage among engineers, often posted in work areas. Does it pertain to software development? The seemingly endless circular debates about software delivery methods lead me to think so. The latest chapter in the ongoing drama is the recent schism between Lean Kanban University’s flavor of Kanban Method and the rest of the lean/kanban community. And the paint hasn’t yet dried on the sumo match between Kanban and Scrum. A few years ago (mid-00’s, as memory serves) the same debate (except for the names of the methods) raged between proponents of Evolutionary Project Management (Evo) and Extreme Programming (XP). Prior to that, we kept ourselves entertained by debating whether RUP was Agile. Before we could do that, we had to settle the debate about the relative merits of Spiral and RUP, of course. And Spiral vs. linear SDLC processes. Tomorrow, next week, or next month, it will be something else. Important questions, all.

Yet, I can’t help noticing, as Ron Jeffries puts it, it’s all the same elephant. When I stopped arguing and started listening to the elephant, I heard it say "Don’t do anything stupid on purpose." What does the phrase mean in the context of software development and delivery? To explore the question, I think it would be helpful to define the terms stupid and on purpose for that context.

What does a collaborative team work space look like?

The following passage from a generally good article by Jon Evans struck a chord with me:

Open-plan offices, in particular, seem an impressively terrible idea. "Open plan layouts create massive distraction, damaging productivity," according to a recent analysis by the U.K.’s Channel 4. See also the related Hacker News commentary, which includes gems like "Most modern office layouts seem to be designed to screw with people’s fight or flight instincts all day," and "I’m a quiet type, and I often need time alone to think and write code and documentation. The ‘rah rah’ social types railroaded us…I am becoming bitter and resentful."

What development methods and practices do you support?

From time to time, something happens that reminds me that our espoused theories aren’t always congruent with our theories in use (see this summary for some quick background info on those terms). The author of an article I had cited as an example of "binary thinking" posted a comment asking how I had gotten the idea that he was pro- or anti- anything. I took the question literally, and started thinking about how any of us might get the idea that another practitioner was pro- or anti- any given software development practice.
