Together with Willem, I’ll be running a workshop about Responsibility Driven Design for the Agile Belgium User Group, in Ghent on 12 March. The objective of this workshop is to show how responsibility driven design takes object oriented thinking and test driven development a step further:

Responsibility Driven Design with Mock Objects

Object oriented design is the art of assigning the right responsibilities to the right objects and arriving at a clean, loosely coupled, and highly cohesive design. Test Driven Development (TDD) will guide you in that direction, but not far enough. TDD helps to get loosely coupled objects, because coupling hinders the test-code-refactor rhythm.

Responsibility Driven Design is an approach that goes a step further. It shifts the focus from state to interactions and responsibilities. It helps to get a highly cohesive, loosely coupled object oriented design – an approach facilitated by test driven development with mock objects.

In this workshop, you will learn how to use the CRC card technique (Class-Responsibility-Collaborator) and mock objects to evolve a design in small steps, by looking at classes and their responsibilities, relations and interactions.

After a bit of presentation and a live programming demo, we’ll run a short coders dojo so you can experience it yourself. The dojo makes this session also interesting if you are already an RDD master.

Interested in this topic, but unable to participate? We offer courses on OO Design, Test Driven Development, Mock objects, and Refactoring in different forms, from short workshops to 2-day courses. Feel free to contact us.

Here are some of my thoughts on time management after experimenting with Do It Tomorrow (see also the overview and time management principles):

• Finishing off a closed list with today’s work feels good. It helps me to get relevant stuff done in time.
• I liked setting my email and paper backlogs explicitly aside as official ‘backlogs’ and planning to process them (little and often). It took away the pressure I felt from the big stacks of papers on my desk and the long list of emails in my inbox.
• I often have emails and other stuff that I would like to do something with, but initially I don’t know exactly what. As a result, I postpone them, think frequently about them, and, after some time, force myself to do something. Then I often find that the actual action is quite easy to do – realizing I’ve wasted time and energy on worrying about it Focusing on doing stuff tomorrow helps me to find the smallest, simplest next action that could possibly work. The trick is to think of the first tiny step I could do to get started or make progress and make it a recurring tasks for the next day(s).
• I’m good at procrastinating on answering ‘difficult’ emails. I have found out that it becomes much easier if I split the work into first writing a rough draft version (where anything is good enough for a draft) and finishing it the next day. I feel much less resistance to taking a minute to ‘just jot down my ideas’ than to writing the ‘difficult’ email. The weird thing is that the ‘rough draft’ usually turns out to be a nearly finished email… 
• Sometimes, I prefer to go with the tasks I feel energy for. Last week for instance, I planned to spend two or three pomodori on end-of-year bookkeeping tasks, regarding it as a recurring task. After I started however, I continued doing it – I felt motivated to finish most of the (boring) work. This helped me to get a feeling of accomplishment and leaves me more time for enjoyable stuff in the rest of the month.
• I also prefer to have time for unplanned things each day, things that come up and/or things I feel energy for. A Will Do list can help to get both the important things done and leave time for unplanned stuff. 
• I’m not sure doing tasks tomorrow works for all my stuff: some tasks that I don’t do rightaway (i.e. today or tomorrow), end up being invalidated or changed after some time by new information. If I would have done the task right away, it would have been suboptimal, like buying at a price that’s too high or bugging people about issues that would otherwise get resolved automatically. Real options thinking would be useful here.  
• I’m keeping the Will-Do lists for planning and doing tasks at home. There it helps me to get all kinds of not-yet-urgent tasks done that I would normally postpone forever. By making a small, feasible list every day, I get things done, without stress.
• For my business, I’m also looking at the new Autofocus system Mark Forster is currently beta testing; I like the name and it looks interesting. Furthermore, I’m working on my “project management” system, to keep track of all my different projects and to make sure that imporant stuff happens. 

So there’s no easy solution for time management. Do It Tomorrow contains a lot of useful ideas, but in the end you’ll have to keep on reflecting what works and what doesn’t work for you, and grow your own system.

In the previous entry, I wrote about the time management book Do It Tomorrow. This post is about the principles of time management that underlie Do It Tomorrow:

1. have a clear vision
2. one thing at a time
3. little and often
4. define your limits
5. closed lists
6. reducing random factors
7. commitment vs interest

Have a clear vision

Have a clear vision of your goals, of the things you want to do and the things you don’t want to do. A clear vision directs your priorities. Setting priorities is only meaningful between projects, not between tasks that have to be done anyway (’project’ is loosely defined here as an activity that leads to some desired result and that cannot be finished in one go).

Your vision is not something static: it will change over time. So frequently revisit your vision, to keep your priorities clear as well.

One thing at a time

Focus, focus, focus! Use for example timeboxing or working with a pair (like pairprogramming) to work in highly focused way. Don’t dilute your focus by having too many projects at the same time.

Little and often

Work on things frequently, in small bits, iteratively and increment, so that results grow over time. If you want e.g. to write a book or finish a Ph.D. thesis, work every day on it. Actually doing something and keep doing it is more important than the amount of time spent.

This works for writing, uncluttering your home or office, bookkeeping, and many other larger activities.

Define your limits

Creative thinking works better within clear boundaries. An example of limits is timeboxing your activities, e.g. using the pomodori technique.

Defining limits is also important for your projects: determine the boundaries (and frequently re-determine them) to get a clear focus of what you’re doing and what you aren’t doing, instead of being busy with a cloud of all kinds of vaguely interesting and possibly relevant stuff.

This week, I’ve started to make a map of all the projects that I currently have and that I want to take on this year. Being an independent consultant, I don’t have an organisational context that sets a lot of boundaries for me so I’ll have to set them myself in order to be effective.

Closed lists

A closed list is a list that has a line under it and that will not change. For every day, you make a Will Do list, a closed list with the stuff that came in the previous day and your recurring tasks. As the list is closed, it will only shrink when you’re finishing items from the list. This will give you a feeling of accomplishment at the end of each day, when all the Will Do items have been checked. 

Anything that comes in during the day and that is not a real urgency, will be put on tomorrow’s list or below the line of today’s list. You’ll first finish all the items above the line, before doing the newly added things.

This approach enables you to plan most of the work you do, so you can work much less reactively and much less governed by self-inflicted urgencies. Your day to day planning will become more predictable and you’ll get early feedback when you’re structurally overloaded.

The Will Do list is limited by your daily processing capacity (so you will need to find out what it is), so you prevent backlogs from building up. If you get more work each day than you can handle the next day, you’ll have to either cut down on your commitments, make your systems more efficient, and/or allocate more time for the stuff on your lists.

Willem asked, what do you do when the telephone rings? It depends: you can answer the call, make a note, and take action tomorrow (unless, of course, it’s about your house being on fire). You can also decide that you won’t answer the phone during certain activities, listen voicemail later on, and get back to the callers the next day. It depends on the nature of your work and your preferences.

Another advantage of closed lists is that you don’t have to prioritise between the items. They all need to be done and if the list is limited by your daily processing capacity, it will be finished. Prioritizing doesn’t make sense for stuff that needs to be done anyway.

Working this way gives peace of mind and reduces waste: you don’t have to spend your energy making difficult decisions about priorities. Prioritizing is waste: it’s work that adds no value, but just increases the pressure on you! You’ll have more time and energy left for actually doing useful stuff.

Forster’s recommendation is to start with the least urgent things first. If work has to be done anyway, why not do it right away?

A bright, grand idea like writing a book is not something you can finish the next day. This becomes a project, a task that recurs (a little attention every day) until the work is finished.

Reducing random factors

By preventing most ‘urgencies’, you will reduce a lot of (self-inflicted) variability in your day to day work. Closed lists system make the underlying systems problems visible. You can’t eliminate all variability and randomness, but you can reduce them substantially, giving you more freedom, making sure your important things get done, and enabling you to handle the remaining randomness better.

Commitment vs interest

You can be interested in a lot of things, but you can have only a limited amount of commitments. It is important to know your commitments, as these provide a framework for your decisions. It’s like the pigs and chickens metaphor used in Scrum (chickens are only involved, but pigs are committed). A pig only has limited ham and bacon it can provide… (the pigs and chickens metaphor has its limitations, but that’s another story)

Looking for ways to get more done with less stress, I recently bought and read Do It Tomorrow and Other Secrets of Time Management by Mark Forster. I’ve started experimenting with it and I like it so far. The Do It Tomorrow system is simple, but not necessarily easy (because it’s about changing your habits). It’s based on clear principles and takes a systems view – focusing on making problems in the underlying systems visible and tackling root causes instead of being just a clever trick. It suits me better than e.g. the Getting Things Done system.

I’ll give my interpretation of what Do It Tomorrow is about, based on what I’ve read and tried so far. Forster nicely summarizes it with the Mañana Principle:

The art of getting everything done by putting it off to tomorrow.

The motto is nothing is so urgent that it can’t be put off till tomorrow. It’s however not about letting things wait until they disappear by themselves! It is about actually doing the stuff that you need and want to do, earlier, with less stress and reduced cycle time (= the time between the arrival or conception of the task/email/thing and doing it).

You get rid of your backlogs (emails, tasks, papers, mail) and set up a system for yourself to keep backlogs away. Backlogs are ‘evil’: they are symptoms of problems in the underlying systems. With systems I mean the systems you use for managing your time and energy, for processing emails and other stuff, the way you manage all your other work and projects. Backlogs tend to hide problems. Stuff waits in your backlogs until it cannot be put off anymore, which makes it urgent without a good reason. In this way, you are driven by the urgencies of the minute, while other stuff in your backlog that does not make enough noise just starves.

Forster states that there are only a few real urgencies that really require an immediate response from you, like your house or office being on fire, your kid being ill at school, or your pc breaking down so that you can’t do your work. Most of our ‘urgencies’ are either misinterpreted as urgent or self-inflicted (caused by letting it wait until the last irresponsible moment). Most of the stuff that comes in can wait until tomorrow.

So the idea of Do It Tomorrow is to set up a system for yourself, in which you handle all of the stuff that comes in today, tomorrow. Of course, some days you get more stuff than you can handle on the next day, but that should even out over time. If not, you have a systems problem that cannot be solved in a sustainable way by just working a bit longer or putting in a bit more effort. The problem is caused by:

• working inefficiently
• having too many commitments
• having too little time for the work

According to Forster, these are the only three possible causes of time problems. Prioritizing and creating to do lists won’t help you in tackling these. 

I see a lot of parallels with lean: you establish flow of all the stuff you do, reduce variability in your work. It focuses on reducing muda (waste, inefficient way of working), mura (unevenness of work, caused by procrastination and waiting until nonurgent things become urgent), and muri (overburdening yourself with too many commitments).

In the next blog entry, I’ll give an overview of the 7 principles of Do It Tomorrow and say something about my experiences. I appreciate Willem for the evening conversations leading to these blog entries.

Portia wrote about Perfect is Poison earlier this week:

Perfect doesn’t exist. Perfect is something we aspire to, it’s elusive by design.

Striving for perfection is a trap for many organisations: the organisation becomes more and more adapted to its context, ultimately fitting perfectly (having found the best practices and the optimal way of working). This also removes all variety from the system however, making it less and less adaptable. This leaves the organisation very vulnerable to changes in its context – and its context will definitely change. This a problem in many Routine cultures.

Assuming a stable environment for IT projects is dangerous: projects are in continuous flux and lots of stuff changes.  IT projects (agile or not) are complex systems (at least the ones that aspire to make a difference). A project changes its context and is changed by its context.

If you look at it in this way, there’s actually no such thing as perfect. Maybe the organisation can be perfect for a moment, fitting its context, but then the world moves on, stuff changes, and the state of perfection is over.

Maybe we should not even talk about continuous improvement, because that presupposes you’re improving towards some goal. Managing a complex system is instead a continuous balancing act – dancing with the system, while learning more and more along the way.
