10x Software Development

Numerous studies have found 10:1 differences in productivity and quality among individuals and even among teams. This blog contains Steve McConnell's thoughts about how to move toward the "10" side of that 10:1 ratio.

New OnDemand Course - 10x Software Development, 2nd Edition

How do you maximize team productivity? Decades of research have found at least a ten-fold—“10x”—difference in productivity and quality between the best teams and the worst. The studies have collectively involved hundreds of professional programmers across a spectrum of programming activities. Specific differences range from about 5:1 to about 25:1, and in my judgment, that collectively supports the 10x claim. Moreover, the research finding is consistent with my experience, in which I have...

New OnDemand Course - Scrum Overview

Hello, Steve McConnell here. We are always updating our Construx OnDemand training, and I’m happy to announce a new course: Scrum Overview. Scrum enables software development teams to address complex adaptive problems, and in this course you’ll learn Scrum’s elements—its roles, events, and artifacts—as well as their purpose: how they’re all bound together to make Scrum hum. In short,...

Agile Transformation - Keys to Success

I wanted to let you know that I've posted a two-part series on Construx's experience with Agile Transformations, pitfalls, keys to success, and so on.  The videos focus on two models that describe the transformation issues we have seen on the ground. You might have seen one or both of the models before, but they aren't often applied specifically to Agile adoption work. The focus of the videos is on showing how these general models specifically apply to Agile transformations. We have...

17 Theses on Software Estimation (Expanded)

This post is part of an ongoing discussion with Ron Jeffries, which originated from some comments I made about #NoEstimates. You can read my original "17 Theses on Software Estimation" post here. That post has been completely subsumed by this post if you want to just read this one. You can read Ron's response to my original 17 Theses article

Understanding Software Project Size - New Lecture Posted

I've uploaded a new lecture in my Understanding Software Projects lecture series. This lecture focuses on the critical topic of Software Size. If you've ever wondered why some early projects succeed while later similar projects fail, this lecture explains the basic dynamics that cause that. If you've wondered why Scrum projects struggle to scale, I share some insights on that topic.  I believe this is one of my best lectures in the series so far -- and it's a very important topic. It will...

17 Theses on Software Estimation

(with apologies to Martin Luther for the title) Arriving late to the #NoEstimates discussion, I’m amazed at some of the assumptions that have gone unchallenged, and I’m also amazed at the absence of some fundamental points that no one seems to have made so far. The point of this article is to state unambiguously what I see as the arguments in favor of estimation in software and put #NoEstimates in context.   1. Estimation is often done badly and ineffectively and in an overly...

#NoEstimates - Response to Ron Jeffries

Ron Jeffries posted a thoughtful response to my #NoEstimates video. While I like some elements of his response, it still ultimately glosses over problems with #NoEstimates.  I'll walk through Ron's critique and show where I think it makes good points vs. where it misses the point.  Ron's First Remodel of my Kitchen...

Human Variation Introduction - New Lecture Posted

In this week's lecture (https://cxlearn.com) I introduce the topic of human variation. I start by describing the general phenomenon of 10x variation. I briefly overview the research on 10x. I describe the problems that 10x variation presents for research in software engineering. I go into the specific examples of the Chrysler C3 project and the New York Times Chief Programmer Team project. And I summarize a few of the software...

Debian Size Claims - New Lecture Posted

In this week's lecture (https://cxlearn.com) I demonstrate how to use some of the size information we've discussed in other lectures by diving into the Wikipedia claims about the sizes of various versions of Debian.  The point of this week's lecture is to show how to apply critical thinking to size information presented by an authoritative source (Wikipedia), and how to arrive at a confident conclusion that that information is not...
