Employer Investment in Employees

Uncle Bob has a pretty clear opinion on who has the responsibility for a programmer’s practice/learning:

Professional programmers practice on their own time. It is not your employer’s job to help you keep your skills sharp for you.

Uncle Bob in The Clean Coder Chapter 6

Here Uncle Bob is talking to programmers, to employees.  What I hear is “don’t expect your employer to help you out.  If they’re not, that’s not an excuse.”

So, my question is, does that mean that employers should not provide any learning opportunities for it’s employees?

Sure, programmers are responsible for their own learning opportunities but could part of that be making sure to find an employer that provides those opportunities?  I personally take some time outside of work to sharpen my saw, but I also look for an employer that cares enough about me to invest in me.

Here is my reasoning why an employer would want to provide learning:

  • Hiring is hard and expensive. If you have people that are a good fit, it’s usually easier to improve their skills than to hire someone new.
  • Learning opportunities at work can inspire people to pursue outside work opportunities.  I have has several people that I work with start attending Utah Software Craftsmanship, Utah Code Camp and Coderetreats because of things that we’ve done during working hours.

What do you think?  Should employers provide opportunities for practice and learning?

If you happen to be a psychic: Quote of the Week

Just started reading Refactoring to Patterns.  Starts off with a good reminder that YAGNI.

When you make your code more flexible or sophisticated than it needs to be, you over-engineer it.  Some programmers do this because they believe they know their system’s future requirements.  They reason that it’s best to make a design more flexible or sophisticated today, so it can accommodate the needs of tomorrow.  That sounds reasonable – if you happen to be psychic.

Joshua Kerievsky, Refactoring to Patterns p.1

Look at the code you’ve written recently.  Were you pretending you’re a psychic?

Retrospectives and Local Maxima

 

Sometimes we feel like this:

image

We are at the top of the mountain!  We’ve climbed, we’ve improved and we’ve made local, incremental changes such that we’re not quite sure where to go from here.  We don’t know where else we could possibly go to move higher.

What we’re missing is this:

image

Yeah, there’s a higher point behind us that we can’t quite see.  In math this is a “local maximum” where we’ve found the “highest point” but only if we constrain the graph we are looking at.

So can we find a global maximum?  Or at least a higher local maximum?  Why can’t we see it?  And how do we get there?

Most retrospective practices (Stop/Start/Keep style activities) will generally get us incremental improvement and will usually lead us to these local maxima.  I’m a big fan of retrospectives and incremental improvement so I’m not bashing these in the general case.  We need to do this once we find a hill to climb, but sometimes we need to find a new hill.

So what can we do to find a new hill?  We need to shake up our team and give them a Jolt.  While I have several ideas how to do that, today I’m going to focus on one: Defining and Focusing on Team Values.

Team Values?

Whether you’ve defined them or not, your team has unspoken values. The value in defining them and talking about them is ensuring that there is common understanding in the team and giving a common language for the team to use.  The values give you a framework for decision making, especially around how you will execute. 

For example, if your team values “time to market” they might take shortcuts and hack something together but a different team that values “maintainability” may take more time to deliver, but will be more maintainable in the future.  (We can debate the relative merits of each of these and if they are really in conflict but this is just an example.)

Team Values Round 1

On my team, earlier this year we came up with eight team values.  When asked what our team values were, we struggled to remember all eight.  We didn’t really know how to focus on all eight or even did a good job of picking one to focus on.

Lencioni’s Value Model

In The Advantage by Patrick Lencioni he describes four different types of values.

  • Permission to Play – These are values like “integrity” that if you don’t have them, you’re not going to be around long anyway so they are really just a required baseline.
  • Core – These are the values that you currently believe in and embody as a team.  They are also central to what the team is and how they do things.
  • Aspirational – These are values that you want to have as an organization but you’re working on.
  • Accidental – These are values that the organization has developed but you’re not quite sure if you like them or not.

This, in some ways, is a Start/Stop/Keep (Aspirational/Accidental/Core) activity, but at a value level that makes you step back and take a wider view.  In our original list, we didn’t differentiate between different types of team values which didn’t give us a place to focus.

Team Values Round 2

So in a recent retrospective, I explained Lencioni’s model of value types and then challenged the team to refine the list to 5 values and classify them as either Core or Aspirational.

The concept of “Permission to Play” gave us a term to talk about certain values that were proposed and exclude them.  Using Lencioni’s model helped us to clarify why we wanted to certain values listed.

We started with the eight that we had originally come up with and I threw out several additional ideas including the XP values, the values from the Agile Manifesto and Software Craftsmanship Manifesto and other sources.

As a framework for voting and subsequent discussion, we used Fist-to-Five voting (we nick named it “Fist voting”) to decide if values were in or out and if they were Core or Aspirational.  While it might seem silly to quibble over such things, I often go back to this quote:

Often the true value of a thing isn’t the thing itself, but instead the activity that created it.

-Dave Thomas

I found the discussion and the clarification of thoughts and terms to be one of the most valuable aspects of this exercise.  We came to a better common understanding by forcing each other to clarify what we meant with different values.

One example of this was one of the original eight values was “teamwork”.  As we talked about it, it seemed like this might be “permission to play” or at least too broad and poorly defined.  So we debated about words.  What word or phrase would better embody what we really felt we had or needed as a team.

Eventually “Team Ownership” was proposed.  The team liked it but the team was split on whether or not it was Core or Aspirational.  This might seem trivial, but the divide produced a valuable discussion around what that really meant.  Half thought “well, we help each other out and pitch in when needed already, seems like it’s Core” while the others thought “we often have our own areas we’re working in and not really collectively owning all the code or even all the tests”.  Clarifying how we wanted to define Team Ownership drove us to decide it was Aspirational.

Now we have them… so what?

Once we defined what our values were, we used a variation on the Values-driven Retrospective.  Specifically we used the Believe Statement format (which is We Believe in [insert value], therefore we will [insert what we do]) to generate ideas of what actionable items to work on.  From there we used dot voting to narrow the field and decide.

The other value that our values has given us is the framework to talk about what and how we are going to do our work in a more focused way. 

I hope that this method can help you and your team to jump off your local maxima and find a taller hill to climb as a team.

Addendum

For those interested, our team values are currently (in no particular order):

  • Core
    • Learning
    • Testability
    • Sustainable Pace
  • Aspirational
    • Ease
    • Team Ownership

They actually ended up very similar to our first eight, but more focused.  As a side note, I fully expect to reexamine these again in the future.  As our team changes and grows, our values will likely need some tweaking.

Agile and the Chasm

In the book Crossing the Chasm: Marketing and Selling Technology Project, Geoffrey Moore discusses the idea that technologies start with early adopters and at some point must “cross the chasm” to majority.

At the recent Salt Lake Agile Roundtable meeting, there was a brief exchange on if Agile had crossed the chasm.

My thought (which is informed by recent experiences with the majority) is that the term “Agile” and some of the practices (Scrum/Scrum-like practices) have crossed the chasm but the values expressed in the manifesto have not.

What do you think?  What has your experience been?

Does the Manifesto matter?

I recently had the chance to interview candidates for a position on my team.  I put together a list of questions that I believed would be a unique and effective way of phone screening candidates.  Without giving away the whole list (I may disclose it later), here are the first two questions:

  1. Tell me something about yourself that isn’t on your resume.
  2. Are you familiar with the Agile Manifesto?

I had two out of seven candidates that I phone screen answer in the affirmative to question 2.  Now not being familiar with the Agile Manifesto isn’t necessarily uncommon, I guess.  But the inconsistency came from the answer to the next question:

“What Agile practices are you familiar with and/or have used?”

I figured the answers would be “I haven’t used any”.  Because if you have done “Agile practices” you’d certainly know what the Agile Manifesto is, right… right?

BUT…

the answers were mostly in the “like, Scrum? Stand ups? Yeah, we do that stuff on my team.”

So… these candidates had presumably been introduced to the term Agile, to some Agile practices but hadn’t taken the time to investigate further, to understand the roots of the Agile movement, to do a quick Google search!  Granted none of them had incredible answers to the Agile practices question, but they did have answers.

I guess I just don’t get it.  I mean, I do.  But I don’t.

Would this matter to you?

CodeRandori.com and AgileCodeGames.com

I recently purchased these domains and while I have plans for them, I haven’t done anything yet.  So I decided to just have them forward here to my blog for the time being.

The plan for CodeRandori.com is to have a “one stop” resource for what a Code Randori is, how to facilitate and some example problems to use.

I’m not entirely sure about AgileCodeGames.com  I was thinking maybe to have a “Tasty Cupcakes”-like site but for coding games (like katas and randori and pairing games) but I’m not sure.

So what do you think?  Any ideas on what to build at these domains beyond what I’ve planned?
