The Most Important Question

I referred to this in a previous post but I want to highlight it here because I believe it’s so critical to a well-functioning team: in a team environment, there is one question that you want all team members to ask themselves every single day.  You need to create systems that remind them to ask that question and systems that give them the information necessary to arrive at the most timely and best possible answer to the question.

The question is this:

What is the single most effective thing I could choose to do today to help the team deliver business value?

So much work is wasted because people are busily doing what was estimated to be the most effective thing when planning was done last week, or last month, or last quarter (but that planning is now obsolete and wrong).  Or maybe they’re doing the work that’s most most personally interesting rather than what’s most valuable.  In any case, if you’re not asking and answering the question every day with up-to-date information, you’re probably doing things that don’t matter.  And that’s threatening the effectiveness of your team and the viability of your business.

That doesn’t mean you need to hop around from task to task with the attention span of a drug-crazed squirrel.  Task switching has its own costs and that needs to be taken into account.  It’s also true that the most urgent thing that needs doing is not always the most important and effective thing you could do.  Of course the evaluation function for “the single most effective thing” will vary from team to team.  The point is to get clear about what your evaluation function is and make sure that everyone is applying it correctly every day using the most current information available.

How well does your team handle this question?  Do they have frequent opportunities to ask the question and make choices about how they spend their time?  Do they have the information they need to correctly answer the question?  If not, why not?  Are there systems in place that encourage people to act on stale information?  If so, get rid of them.  Does your team’s view of the world frequently diverge from reality?  If so, figure out what causes that to happen and fix it.

Do the most effective thing.

Configuration Scripts For Lazy Developers

Laziness is a virtue

I recently paved my laptop and set it up again from scratch.  (I wanted to get rid of accumulated corporate network goo.)  I always dread doing that because it takes so long to get everything installed and configured the way I like to have it, especially since I use non-default settings for several things.  It’s even more obnoxious because I regularly use multiple computers and I want to have all settings the same across all of them.

Well, in the spirit of “laziness is a virtue”, I decided to start scripting some of this stuff so that I don’t have to do it by hand every time and it’ll be easier to apply a consistent set of settings across all of my machines.  A full-blown automated configuration system would install software and do absolutely everything for me but I’m starting simple with some Powershell scripts that configure the behavior of Windows Explorer, the console, Git, and Notepad++.

(I have a feeling that there are already tools/projects/script libraries out there that do this sort of thing in a much more complete way but I didn’t run across anything during a quick web search.  If there’s something I overlooked, let me know in the comments.)

I thought I’d share my configuration scripts/files, not because the configuration settings I choose to use are all that interesting (they’re not), but because the mechanism of where to find these settings and how to script them may be interesting for others who want to do something similar.  You can find them at http://github.com/SaintGimp/ConfigurationScripts.

How I use them

So here’s the way I’m using these scripts:

  1. I keep them in a Configuration folder inside my WindowsPowershell folder which contains my Powershell profile, Powershell Community Extensions, and other useful Powershell stuff.  I sync the WindowsPowershell folder across all of my computers using Windows Live Mesh so that when I make a change to any of the files on one computer the change shows up on all my other computers automagically.
  2. When setting up a new computer I’ll first install Notepad++, Git, and Windows Live Mesh, then sync the aforementioned WindowsPowershell folder.
  3. I start an elevated Powershell console and cd to the WindowsPowershell\Configuration folder.
  4. I run all of the Configure-[foo] scripts in the folder.
  5. When I change something about my preferred configuration, I’ll update the script files and run them on all my other computers the next time I use them.

What they do

  • Configure-Console.ps1: I like to use the Consolas font and to use several other non-default settings for my console windows and I want my cmd consoles to look different than my Powershell consoles.  To accomplish this I found that I need to copy modified Powershell shortcuts (which contain console settings) into the Start Menu folder, plus load other stuff into the registry for default settings and for Powershell instances that aren’t launched through the shortcuts.  The registry settings are contained in a .reg file I exported from regedit after I got everything set up the way I want it.
  • Configure-Explorer.ps1: I use a command from Powershell Community Extensions to add an “Open Powershell Here” context command to Windows Explorer, then I import a bunch of registry settings for view options and start menu options.  Finally I add Notepad to the Send To menu and remove several other things that I never use from that menu.
  • Configure-Git.ps1: This sets several Git configuration options including a prettified version of log (git lg) and Notepad++ as my default editor.
  • Configure-Notepad++.ps1: I have a small shim that I register as a debugger for Notepad.exe which runs Notepad++.exe instead.  I prefer doing that rather than hunting down every place that Notepad.exe may be invoked in my tools and changing the command.  Next I change a couple of Notepad++ settings to the behavior I prefer.

There’s obviously a lot more that could be added but I’m going to do that on a “pain threshold exceeded” basis; that is, when configuring something by hand annoys me too much then I’ll sit down and figure out how to automate it.

Why The Standup Meeting Is Important

High-bandwidth communication

If you’re trying to do agile software development, high-bandwidth communication is incredibly important.  It’s almost impossible to overstate the urgent need for team members to be in constant communication with each other and to know what’s going on at all times.  That’s the only way people can make the right tactical decisions and adapt to the current situation rather than merely operate according to their understanding of the situation as it was a few days ago, or last week, or last month.

There are several ways to encourage frequent and high-bandwidth communication.  Having a co-located team room is probably the best possible way to do this, though I’ve never had the pleasure of experiencing that for myself yet (but I will soon!)  If, like all my teams up to this point, you’re sitting in individual private offices, then a daily standup meeting becomes super important.  I often get pushback on the standup meeting, with people questioning why it’s necessary and whether the daily interruption is worth it, and here’s what I tell them.

The most important question

I’ve worked at Microsoft for a long time, working in several different areas of the company, and in that time I’ve observed that we often optimize for the wrong things.  Historically, Microsoft has optimized heavily for individual developer productivity (in the sense of lines of code written).  However, Microsoft doesn’t usually have a problem with devs writing code too slowly; most of our product code bases are enormous.  We’re awash in code.  What we actually struggle with is that we write the wrong code, or code that doesn’t work right, or we write a bunch of individual pieces of code that don’t interact well when we try to fit them together.

It turns out that an engineer’s job is not just to write software.  His or her job is to deliver value to customers in a timely manner, make a valuable impact on the business, and ultimately to earn money for the company.  Writing software is an essential step but it’s not actually the end goal.  Delivering business value requires more than just individual code-writing prowess.  It requires frequent, consistent communication across the entire team so that we’re all pulling in the same direction at the same time and doing things that actually matter.  It requires a team-oriented mentality; we don’t make commitments as individuals, we make commitments as a team and we succeed or fail as a team based on the value of what we deliver.

With that in mind, the point of the standup meeting is not to communicate status to managers.  We could do that perfectly well once a week over email.  The point of the daily standup is to communicate together as a team so that every day each team member can ask and answer the question, “What is the single most effective thing I could choose to do today to help the team deliver business value?”

That’s a very powerful question to ask.  Contrast that with the traditional Microsoft model of asking yourself, “What do I need to do to finish all of the tasks that have been assigned to me?”  To answer this traditional question, you don’t really need to know what anyone else is doing or what’s going on across the team.  You just crank through your assigned work.  The problem is that the tasks that were assigned to you might grow stale very quickly; that is, the value that we thought a task had when it was written down might not be the value it has now because reality has a way of changing things over time.  If you let “the plan” diverge too far from reality, you end up building software that doesn’t matter.

Avoiding wasted effort

Have you ever had the experience of spending months working on a piece of software only to have that software never get deployed/sold/used?  I certainly have.  I’ve seen it happen for all of the following reasons:

  1. When finished, the software didn’t solve the problem the customer wanted solved, either because: A) you never correctly understood the real problem in the first place, or B) you understood the original problem but it evolved and changed between the time you started and the time you finished, so the software you wrote to meet the original problem became ill-fitting.
  2. You ran out of time in the schedule and while you had a lot of code written, the pieces that were finished couldn’t be easily assembled to solve any problems on their own, so the whole thing was useless.
  3. You built good software that solved a real problem but your customers weren’t aware of what you were building or how much progress you were making so in the meantime they ran off and invested in some other solution instead, making your solution irrelevant.
    The daily standup meeting (and the other sprint meetings we have) are intended to avoid those failure scenarios by creating frequent opportunities for communication.  This communication is intended to make each team member aware of exactly what the state of the project is right now, today, so that we can make the best possible choice about how to help drive the team toward delivering real value.  The task board is in a big visible location and is updated every day so we can see what’s been done, what’s left to do, and where we need to load-balance.  We try to have a customer representative on hand so that we immediately hear about any changes in what the business needs from us and we can get good guidance when we have to make hard tradeoff decisions.  We listen to what each team member is doing because we often pick up serendipitous pieces of information that save us far more time than the 15 minutes it costs us.  Examples:

Person A: I’m struggling to solve this problem.

Person B: Oh, I solved that same problem last week.  Here’s the solution.

Person C: I’m working on this particular task today.

Person D: Hey, I’m working on this other thing and I just realized that’s going to drastically affect your work.  We need to talk.

Person E: This really important story is going more slowly than we thought it would.

Person F: The stuff I was going to work on isn’t as valuable to our customers; how can I help speed up the important story?

Person G: I chose to implement this new feature in this certain way.

Customer Rep: Hmm, I don’t think that’s going to work well for us.  Have you thought about…

Talk to each other

It’s remarkable the lengths that software developers will go to in order to avoid talking to their teammates.  Many of us are introverted in the first place (I certainly am!), plus our industry still has this conception of the mythical cowboy coder who locks himself in his office, getting pizza and soda slipped under the door, and every once in a while code occasionally emerges.  I’m not sure that model ever worked all that well, but in any case we (should have) outgrew it a long time ago.  It’s simply not workable these days when you consider the speed and volume at which our customers expect us to deliver value.  Talk or die.  The choice is that simple.

A New Adventure

Wow.  After almost eighteen years at Microsoft, it’s time to try something different.  I’m moving to Blade Games World to work as a senior developer on Jumala!  I’m ridiculously excited about this opportunity, but I’m sure it’s going to be quite a ride moving from a ~90,000 employee behemoth of a corporation to a 14 person startup (well, 15 now, with me.)  Joy and terror in equal measure.  I’ve been told to expect quite a lot of “detox time”, and I’m looking forward to experiencing and blogging about some of the differences.  Oh yeah, this is going to be awesome!

As part of this move, I’m transitioning my blog from MSDN to SaintGimp.org.  I expect that my old posts will remain up on MSDN indefinitely and if you want to read my older material, please check that site, but all new posts will be on this site.
