Many people who work in software development today have heard of the practice of pair programming, yet it still only has patchy adoption in the industry. One reason for its varying acceptance is that its benefits are not immediately obvious, it pays off more in the medium- and long-term. And it's also not as simple as "two people working at a single computer", so many dismiss it quickly when it feels uncomfortable. However, in our experience, pair programming is vital for collaborative teamwork and high quality software.
There isn't a simple dichotomy of remote versus co-located work, instead there are several patterns of distribution for teams each of which has different trade-offs and effective techniques suitable for them. While it's impossible to determine conclusive evidence, my sense is that most groups are more productive working in a co-located manner. But you can build a more productive team by using a distributed working model, because it gives you access to a wider talent pool.
Get good audio, use gallery view, mute if not talking, and welcome the cat.
We, and our colleagues, are often called on to perform architectural assessments for our clients. When we do this, the architects involved with these systems will talk about the performance of these systems, how resilient they are to faults, and how they are designed to evolve to easily support new capabilities. The elephant that rarely comes up, however, is how different systems contribute to business value, and how this value interacts with these other architectural attributes.
An inception is an activity done at the start of a project to gather together the people involved and set a common direction and working style for the on-going work. The lean inception is a focused form of inception, which can be done in a single week. During this time we understand the key features and customers for the product, and build a canvas to formulate the characteristics of a Minimum Viable Product.
A while ago I was chatting with a post-doc on his way to an academic career. He was asking me about research topics wanting my input as he felt I could inform him on what would be research of practical use. I wasn't very helpful, but I did mention that the best way to do this would be to spend some time in industry to get a feel of how software development works in the wild and what problems could do with some research effort. His answer to this thought was very troubling.
Alignment maps are organizational information radiators that help visualize the alignment of ongoing work with business outcomes. The work may be regular functionality addition or technical work such as re-architecting or repaying technical debt or improving the build and deployment pipeline. Team members use alignment maps to understand what business outcomes their day-to-day work is meant to improve. Business and IT sponsors use them to understand how ongoing work relates to the business outcomes they care about.
When people use the term 'software architect' they are using a metaphor from building construction to help people understand the architect's role.Ironically in doing this they misunderstand the actual role of a building architect.
With the growing interest in data analytics and visualizations, we're seeing more effort put into interesting visualizations that allow people to draw insight from data floating around in an organization. Most of these dashboards are aimed at individual usage, but there is a growing tendency to use them for a more communal purpose.
Here's a common misconception about agile methods. It centers on the way user stories are created and flow through the development activity. The misconception is that the product owner (or business analysts) creates user stories and then put them in front of developers to implement. The notion is that this is a flow from product owner to development, with the product owner responsible for determining what needs to be done and the developers how to do it.
Agile software development has broken down some of the silos between requirements analysis, testing and development. Deployment, operations and maintenance are other activities which have suffered a similar separation from the rest of the software development process. The DevOps movement is aimed at removing these silos and encouraging collaboration between development and operations.
From time to time during a meeting or workshop, it's good to get votes on a number things in order to rank or choose a subset. A quick and nice way to do this is dot voting.
Open Space is an approach to help you put together self-organizing conferences. I was first introduced to it by Norm Kerth in 1997 and have since seen it used, and used it myself, many times. It seems to work well in small scales, groups of a dozen or two people, and at larger scales of one or two hundred. I've seen it for periods of one to three days. I'll describe it with variations I have seen: Crested Butte is a small annual workshop of around 20 people, Agile Universe 2002 had about 100 or so at the conference with Open Space in one track (they've continued to do this since, but I've not been able to get there), foocamp did this with a couple of hundred people. The technique was developed by Harrison Owen and is well described in his book.
Pair Programming is a software development practice that has the developers work in groups of two. All serious code is written by two programmers, typically sitting side-by-side with a single monitor, often with a single keyboard. As they add code, they discuss each step together.
A bunch of common misconceptions about pair-programming.
All agile methods stress the importance of direct interaction between the developers of a system and customers who are its eventual beneficiaries. The agile manifesto said "Business people and developers must work together daily throughout the project", which is there to stress the high frequency of interaction. Extreme Programming stresses this through its practice of OnsiteCustomer.
A project timeline is a valuable thing to produce during a project retrospective. A timeline should show the various events that occurred during the project, and how they affected the project.
A common thing you find in agile projects is that the development team sits in a single open team room. It was advocated early on in Extreme Programming and called out as one of primary practices in the second edition. Agilists favor a open team room as it promotes lots of informal and deep communication between people on the team.
If you're using XP style planning, you need to get rapid consensus estimates from developers. Throwing the estimates lets you quickly tell when developers have same similar views on an estimate (so you can note it and move on) or if there is disagreement (when you need to talk about the UserStory in more detail.
