After my presentation last night at the Detroit PMI chapter, an attendee asked me, “Is context switching really as bad as you say it is?” Yes, it is. I believe Weinberg’s estimate of losing 10-20% of possible work-time every time you attempt to take on one more project. And, if you read Hal’s entry today, […]
Via Steve Norrie’s weblog, I found Kovitz’s “Hidden Skills that Support Phased and Agile Requirements Engineering”. In phased development, projects promise large feature sets to a customer for future delivery. In agile projects, the requirements are refined over numerous little conversations with the customer, day in, day out. Kovitz claims the skills required for agile
On the AYE conference wiki, Jerry Weinberg said this: “no iteration should be so big that you can’t afford to throw it away if it doesn’t come out right in the end.” The longer the iteration, the less likely you can recover the project (or re-steer it, or re-guide it to an appropriate direction).
Bloglet subscribers saw two posts from me Friday. They saw the post I published *and* the post I saved as a draft. Surprised me. Since I know about this feature, I’ll work around it, and compose future drafts somewhere else. This isn’t a big-deal problem for me. But it was a surprise, and a
In Sunday’s Boston Globe View from the Cube column, Lisa Liberty Becker claims “Telling the truth can be hazardous to your job”. She goes on to talk about her husband, a performance test engineer, whose manager buried his reports, because “they [the reports] reflect poorly on the job he’s done.” The result? Bad product performance,
In my travels last week, I contracted a cold. And of course, life doesn’t stop just because I have a cold and my brain doesn’t work. I still have writing, phone calls, consulting, and driving to manage. I managed to ask for help with the writing. As soon as anyone heard me on the phone,
Earlier this week, I was at SPC teaching about project requirements and project management. If you haven’t thought about lifecycles, consider the differences between these kinds of lifecycles: Linear: Waterfall and waterfall with feedback Iterative: Spiral, where the whole product is up for grabs each time Incremental: Where you add to the product in pieces
I’m at the Software Development conference this week. One of the hot topics I discussed in my presentations and with attendees during and after the talks were about context switching and multitasking, Focused Performance and Breakthrough Thinking on Worker Productivity and Multi-tasking Makes you Stupid, studies say.We agreed that: several pieces of work at different
I was on the phone this morning with a senior manager. He was describing their current project: “Well, we’ve got 25 people: 12 developers, 6 testers, 2 writers, 4 support people, and 1 project manager.” I asked about the managers of the developers and testers. “Oh, the dev manager is running the project. We
I seem to have a vision theme happening this week 🙂 How many kinds of review do you perform on your project’s work products? Especially with software projects, it makes sense to review interim work products, so you have some idea about how good the final product could be. Sometimes when I ask project
