There is a general trend and desire to make work more collaborative. Yet when I ask teams to draw a diagram of how they work, they often come up with something like this (I’m simplifying it):
In this view, the workers form an assembly line. But their work doesn’t really flow like an assembly line. For example, a Software Developer may find a logical inconsistency in a feature specification and send the work back to a Business Analyst. A Quality Assurance specialist may do the same when testing the implemented software. The BA will update the spec and send the work back to QA. QA may find a bug in it and send the work back to the Developer. The Deployment Specialist may find something in the code to be an impediment to deployment. The Developer then makes the necessary change. The code now needs retesting, so it goes back to QA, after which it goes again to Deployment.
So the team members draw many arrows going back and forth between them to show all these handoffs.
Some try to visualize this process on a board they call “kanban”:
Then they ask, what if, for example, testing hands the work back to BA or Dev? Should the card stay in its place or move? What if we have WIP limits? (Those numbers in the column captions.) What if that column is already filled up to the limit and another card needs to move back?
Is There a Better Way?
This problem is fairly common and rooted in the misunderstanding of the nature of professional-service work. Rather than a series of handoffs between specialist workstations, it is mostly about creating information and knowledge. It may be limiting to try to make such process look like a block-diagram.
In our example of software feature delivery, the following knowledge may get created, not necessarily in this order:
- the exact configuration of the production environment (OS, Web server, database server, third-party software)
- key examples of how the software feature will behave, use cases, acceptance criteria, executable specifications, etc.
- how to integrate the new feature with the pre-existing software functionality (upgrade procedures, data migration, etc.)
- what will design and implementation of code exactly look like
- what tests are needed to support the implemented code
- how the integrated software behaves with respect to its performance and other quality (non-functional) requirements
- results of usability tests and exploratory testing sessions
Anyone in any professional service field can come up with their own list of knowledge they create in their own delivery process. When the work is complete, all of such knowledge is there. But when we only get started working on a request to deliver something, it is not there yet.
If we tried to visualize the process of accumulating this knowledge, the result could look like this:
In this example, specification activities dominate the early phase of the delivery process. The Business Analysts may lead the analysis of the feature, decomposition, fleshing out requirements. But other specialists can contribute at the same time. Testers may help turn acceptance criteria in to (executable) tests. Deployment specialists and Developers may weigh in on what may have what impact on the codebase and infrastructure.
This activity produces a lot of knowledge from the start, but it fades eventually. We can’t analyze our way to delivery. So, code construction becomes at some point the main way to accumulate knowledge.
A lot of code construction falls on Developers’ shoulders, of course. But others can help, too. Requirements may still need refinement and clarification (hello BAs). A Tester may take the partly finished software, test it and give feedback to a Developer. Developers can collaborate with Deployment specialists to see how the emerging code changes may impact deployment.
But this activity will fade too. We can’t make further progress by polishing the code. So, we switch to testing it and focusing on getting any remaining bugs out. Another knowledge-creating activity begins to dominate. Testers lead it, but they get help from Developers fixing bugs, and others as well.
Note that the three inflection points in the new process diagram are not handoffs between functional specialists or departments. They are changes of the dominant activity and the corresponding shifts in the collaboration pattern.
We don’t have to look at processes as networks of specialists and handoffs. When trying to understand our processes visually, we don’t have to diagram them as boxes depicting the specialists and many arrows connecting them every which way.
We can instead consider our delivery process to be about information arrival and knowledge creation. By asking ourselves, what activities do we perform to discover knowledge to deliver what we are delivering, we can visualize our process as a sequence of collaborative activities.
In the next several posts, I would like to give some examples of such Knowledge Discovery Process maps, mostly for processes outside the world of software delivery (UPDATE: I’ve posted two such examples, in addition to the software development process example above. One example is from the field of entrepreneurship/lean startup and one from training and courseware).
I also need a series of posts to give guidance on how a process coach can go about mapping such processes with real teams of professionals. For those using kanban systems, this approach has some implications for how to design and operate those systems.
