Stand-ups – We can make them better…

I’ve been thinking about how to get the most out of stand-ups. They are something that all the teams that I have been on do every day, but  how often do they actually meet the real goals of a stand-up? I spent some time thinking about how, instead of just rattling off the usual status update, we can really think about how to best use this time. Not only to communicate  with and learn from the team, but also how to provide that daily re focus on what the team needs to do today to get awesome features into the hands of users. I propose some different questions to think about and frame your updates with during stand-up.

While I was hunting about the internet looking for inspiration, I came across Jason Yipp’s article on Martin Fowler’s Blog – It’s Not just Standing Up. There’s loads of great stuff in there, but specifically what jumped at me was the goals of a stand-up.

 The Goals of the Daily Stand-up are GIFTS

There are several goals for a daily stand-up  meeting:

  • To help start the day well
  • To support improvement
  • To reinforce focus on the right things
  • To reinforce the sense of team
  • To communicate what is going on

As a mnemonic device think of GIFTS:

Good Start, Improvement, Focus, Team, Status

I also came across this from Agile Coaching by Rachel Davie and Liz Sedley. A good way to sanity check how your stand-ups are going.

Signs of a healthy stand-up

- Is everyone engaged, motivated and excited?

- Are they making progress and working on high-priority tasks?

- Are they working together and helping each other?

- Are they able to concentrate and do their job without disruptions?

Reality of what many stand-ups tend to be and some of the problems

I think that it’s easy to say that you are ‘doing standups’, everyone goes around giving their 3 question updates (what I did yesterday, what I am planning on doing today and do I have any blockers), but  you have to ask how effective they are. Was everyone listening to each other? Do you even remember what each person said? Did you learn anything from stand-up? Do you have a better sense of where in the lifecycle any particular story is?

Just like other processes that the team follows, stand-ups should be continually improved and tweaked.

So. I don’t think that the 3 questions above are enough. I think they are great to get the team started, but teams often grow out of them quickly. As long as you keep the goals in mind, you can change the structure to be whatever you want it to be.

Why aren’t they enough? Some reasons:

  • There is too much talk of ‘I’.
  • Lacks focus on getting stories to ‘Done’.  Ultimately the team should be focused on how to get the best, most useful features into the hands of it’s customers, I would like to see updates the revolve around how to achieve that.
  • Too easy for people to hide behind them, robotically answering and it’s easy to lose emphasis.
  • The language is quite passive. Rather than stating what your blockers are, why not focus on what you are doing to get rid of them?

The differences may seem subtle, but the language a team use can totally change the team’s approach.

How to make them better?

Don’t think of it as a status report, more as a chance to communicate with and update your whole team at once.

Explore different formats of standups. I find that ‘Walk the Wall’ works quite well to ensure that everyone is focused on what needs to get done to get  features out the door.

Start to move away from the 3 basic questions. Talk with your team about what kind of updates you would like to hear during stand-up that would be most useful to everyone.  Change the language to be more proactive.

Perhaps think about framing your updates using the language below:

  • What am I doing today to get cards moved across the wall towards “Done”?
    • Ensures that the focus is on activities that directly relate to helping to progress work.
  • What remaining work is left? When am I likely to move it to the next state?
    • Helps downstream roles to know when to expect new work, helping them plan better. Gives the whole team the sense of where the story is in its lifecycle.
  • Meetings? Would the team benefit from hearing a summary?
    • I forever hear “I was in meetings all day”,  hopefully the meetings were project related, so share what happened. People want to know…
  • Did you learn something yesterday that people might benefit from knowing?
    • Help the team become more efficient, by sharing things that you have learnt. It may prevent someone from making a similar mistake, or struggling with something someone has already figured out. If it prompts interest, have a post-standup huddle for people to hear more.
  • What am I doing to remove/fix blockers?
    • This is an important language difference from the standard update.  Don’t wait for people to remove obstacles for you, see what you can do yourself to work round them or move them yourself, or even other peoples. It’s more often than not quicker than waiting for someone else to do it.
 So I prepared the following ‘cheat sheet’ to help you think about your update. You could even stick this up on the story wall itself to act as a memory trigger.

Gender Diversity on Teams – Roundup

Wanted to keep a note of a bunch of articles and books that I found recently around studies about gender diversity on teams. Prompted by a discussion with a programme manager at an investment bank and then subsequently with my fellow ThoughtWorks colleague Nic Ferrier

I found these often quoted “facts” and was trying to hunt down their sources…..

Reflections on my last gig…

I have just rolled off of my project of the last 8/9 months, and thought it was a good point to reflect on my time there.

Once again I had an awesome time. I learnt a lot, met some great people, made some good friends, watched people grow, and most importantly contributed to a great product. There were a lot of highlights, too many to name them all, but here are 5 I picked out.

Non-hostile atmosphere.

The whole team was respectful of each others ideas and skills, open to change and new ideas and a lot of fun. One of the first projects where change has not been outright resisted and refused. As consultants I can see that it’s natural that our presence on a team can cause hostility, but we’re here to help, honest! This lead to a much more productive and more pleasant working environment, allowing people to try new things and bring their ideas to the table.

From the moment that I got there I felt like there was space for my ideas and people were ready to listen to them and give them a go. Wonderful feeling.

It sounds like a small thing but its really not. When a team is willing to change the way it thinks and embrace new ideas, everyone can contribute to that success, it’s not just the persistent, rebellious people (which is often the role that ThoughtWorkers have to take) who can make change happen but there is space and support for everyone to have ideas and change the way things happen.

Feature Leading. Our tech lead was comfortable letting some of us lead a few of the features, which was great. I got to look after the online sales feature we added and an emailing piece. It wasn’t so much as an official thing but more an organic thing. As well as being involved in writing the code, I helped with analysis, spent a lot of time talking to the teams that we were integrating with, kept an eye on and helped out with testing and deployment and generally provided a consistent technical vision for the whole feature. It’s great experience for people who are moving towards becoming a tech lead, without the pressure and responsibility for being the actual tech lead. I found it really energising to have such focus on one feature.

Coaching / Mentoring.

I went to a leadership academy event recently where one of the speakers said that you are not a great leader unless you have pulled people up with you. That has really stuck with me. What kind of leader can you claim to be, if you haven’t helped other people learn and grow?

The client had a female developer on their team who had never met another female developer before she met me. She is also very talented and passionate about technology with some great potential. I spent a lot of time with her coaching and mentoring, and this relationship will outlast the client engagement. I get a massive amount of satisfaction helping others reach their goals and look at the world in different ways. Also being able to provide the support that people need to grow.

I also tried quite hard to make sure that I was giving “in place feedback” i.e. immediate feedback in a situation, mostly whilst pairing etc. One of the other TW Developers on the team commented that he heard me doing this often and learnt a lot from just listening. Need to do this more though. Especially when there are more “heated” pairing situations.

A positive attitude can go a long way.

Generally I’m a pretty positive person, and I got a lot of feedback about how this changed the whole atmosphere of the team. It only takes one consistently negative person on the team to start bringing the entire mood down. Remember this and try and look at situations positively and with energy.

There is more to being a developer than just writing code for the story you’ve been given.

As a developer, you are responsible for getting features that help the people using them into the hands of the people using them. It is your job to push back if you think requirements don’t make sense. It is your job to ensure that the software you are producing is of a good quality. You should not just be coding whatever you are told to without questioning anything. So as well as writing code, be part of the requirements definition, the testing, the conversations with stakeholders, with the people that are deploying your code if it isn’t you. Software that is not in the hands of the users and being used is useless.

As well as advocating the above, I spent some of my time on the team championing and facilitating the retrospectives, launching lunch and learns, being part of the inception, and countless other things that weren’t strictly in the remit of a typical “developer”. For me this is normal as they are things that I enjoy, but I don’t think this was the kind of developer that many of the client devs had met before! I hope that it has influenced them a bit.

Bringing visibility to code quality metrics

It’s often hard to measure whether or not the quality of your codebase is improving. It’s also very easy to become overwhelmed by software quality metrics. With so many, you stop paying any attention.

One of the metrics my current team has been paying a lot of attention to is a “duplicate count”. It’s a measure of how many lines of duplicated code you have in your codebase, both in the test code and in the production code. Team City, which we are using as our Continuous Integration server, has a built in duplicate count, so that every time you check in you can see whether it has gone up or down. (The way that it counts is sometimes a bit strange… but I won’t focus on that!) You can make sure that the build fails if it goes over a certain number.

We were trying to focus on “improving the quality of our test code”, especially our high counts of duplicates within our test code. As this one was easy to measure, we thought we’d focus our efforts on a single metric and consciously reduce the number with each check-in.

Feeling particularly arty that day, I decided to create a physical counter that we could use to measure how we were doing. I created one counter that I put in front of the build monitor. Leaving the numbers to be coloured in as people got to them. This would then be flipped over as people reduced the numbers.

I also created a summary of the numbers to put on the story wall, so that at standup we could always check on progress. Noting what the number was at the start of the week and then what the number of duplicates was for that particular day.

It worked amazingly well. Suddenly this group of grown men were enthusiastically running over to the build monitor to change the counter as they reduced the duplicates. Cheers would go up when a pair checked in code that reduced the number. Turns out “gamification” is a real motivator. Before I knew it, people were getting shout-outs at standup for being particularly good duplicate reducers that week.

Having the additional counter on the main story wall meant that people outside the developers were aware that we were paying attention to the quality of our code and actively trying to improve it. It has now become part of our daily standup routine to talk about it.

The counter worked so well, that we then introduced one for the number of warnings in the code base. Pick a quality metric and try it!

Git for Beginners – Team Lunch and Learn

Our team has just embarked on “Lunch and Learn”s. (A time for the team to get together over lunch and learn about something new). For the first one, my colleague Tom and I volunteered to teach the team to use Git…

Our development team was previously all located in the UK, but we are about to go distributed with teams in both India and the UK.

We are working on a .Net stack so of course, (shudder) we are using TFS. Due to the team changing to be distributed we are having to look at more distributed friendly source control systems, and thankfully Git is on the table.

Now I am definitely still a relatively Git noob. I was introduced to it on my last project, and we used it pretty extensively for a year. Now, I hate working without it. I think it’s changed the way that I work, so it’s hard to go back to the TFS dictated way of working.

We are planning on doing two sessions. This first one being just on the very very basics for someone who has never used Git or another distributed Source Control System. Literally, this is how you get stuff out, change stuff, and get it back in. Hoping nothing goes wrong.

Anyway, we bought pizza for everyone, to keep them happy, and quiet.

The first part of the session we did in a meeting room with whiteboards. Tom talked about some of the high level concepts of distributed source control systems. Along with a brief description of how it differs from TFS ***. Tom also talked through some of the key terminology that people would need to get used to. i.e. working trees, remote repository, the index/staging etc.

My job was guiding the team through the workflow that we’ll be encouraging. I chose to first explain the workflow we would be using, away from the computers using pictures, to ensure that everyone listened and understand why they were doing each command. I was worried that everyone would be distracted and race ahead without considering what they were doing with a shiny new toy in front of them.

Now I know that there are two different schools of thought out there. Local branches or committing on master. I was taught to use Git using local branches so that’s what I’m more comfortable teaching. Plus it means that your master branch is always clean, gives you a bit more of a safety net, but also it forces you to change the way that you are working, not just doing the same workflow you did in TFS or SVN. It forces you to start getting used to the concepts that really make Git powerful.

It went surprisingly well. I was expecting a lot of fear and resistance, but actually it create a great new energy around the team. Everyone rushed back to the computers to try out what we had been showing them, and it started a lot of good discussions.

See the following post for my detailed description and walkthrough of a sample workflow with Git.

*** to keep the “but in TFS…..” To a minimum, I asked everyone to keep an open mind and if anyone who wasn’t presenting brought up TFS they’d have to do star jumps in the corner.

GHC 2012: How to Influence without Authority, and Why It’s Important

These are some notes and thoughts from one of the sessions that I attended at Grace Hopper this year.

Dictionary definition of Influence. - The capacity to have an effect on the character, development, or behavior of someone or something, or the effect itself.

Inherently, you don’t need authority to influence.

What do you need to be able to influence?

- Relationships - Get out into the hallways and meet people… Learn what their goals are and figure out how you can help them advance those goals. Do your job well and build a reputation for yourself.

- Trust. Takes time to build, very easy to break.  You get this by doing what you say and saying what you do. Be consist in your approach to things.  Reciprocity is important. Give as much as you ask. Takes time. Not a one off thing you try to achieve.

How do you influence?

Become good at summarizing, be concise, make sure your ideas are based in fact. Consider your audience. Change the length and depth of your data depending on who your talking to.

What’s in it for them? If people find nuggets of their ideas in your plan, they will want to be bought in to it.

Ask questions. Ask short questions, give people a chance to tell you what they think. Make an emotional connection and find out shared values. Ask open questions, avoid leading questions, not yes/no questions.

Now i’ve always had a bit of an issue with session’s on how to influence people. We had one when I first start at ThoughtWorks at TWU. I’ve always thought there is a very fine line between influencing someone and just plain manipulating them. In my rose-tinted world I hope that you don’t need to consciously try to influence people if you are leading by example and have everyone’s best interest’s at heart. If you are genuine and achieve great things, it will change the way people around you act.

Thankfully someone in the audience asked just this question: How do you make sure you’re not coming across as being manipulative?

Avoid one sided conversations.  Present your idea and ask for feedback.  Focus on what is in it for them.  Respect “No.”, but try again.  Make sure that you are “perceived as trustworthy”. (<- shouldn’t you just BE trustworthy?!)

What do you do when you are dealing with someone who ‘needs’ to feel like they have that authority over you?

Make friends with people who are friends with them and ask their advice. Ask how can I talk to them in a way that they will listen to? Make sure you are advancing them in their goals as well. “Their ego is their teddy bear and don’t take their teddy bear away from them”.

As long as you don’t care who gets the credit you can go along way.

 How to influence what you are working remotely?

Try to meet at least once. Phone and Skype become easier once you have met face to face. Talk about non work stuff to create a personal connection. Get into a conference call 15 mins early and chat, make it known that that’s what you do.
