The best way to understand where you are is to look at your value stream. The value stream can be thought of as the flow of work that takes an idea to the point of realization of value. Notice that we talk about realization of value because mere delivery is of no value. We must attend to the time from start until we or our customers realize value from our efforts.
To understand this, consider a common organization’s structure:
Figure 1: Common organization structure
Most organizations exhibit some form of hierarchy. In this type of structure, it is natural for managers to consider if there people are properly utilized, being product, doing quality work and are working on the right things.
However, realizing value does not occur in a silo. Our work typically goes across an organization as shown in figure 2.
Figure 2: Work flowing across the value stream
In figure 2 the red arrows are the actions of getting approval. Note that these actions in and of themselves add no value. Also, a real value stream would not be such a nice flow from left to right but would go forwards and backwords. When we consider time from start to realization of value, we realize we need to attend to time-to-marketm, our eco-system, visibility, effects of upstream groups on a team, and the effects of a team on downstream groups. The value stream is where the work actually takes place, as illustreated in Figure 3.
Figure 3: The value stream.
By comparing figures 2 and 3 we can see that natural conflict that arises. We manage our work one way but it actually flows a different way. This is illustrated in Figure 4.
Figure 4. We manage one way even though our work flows another way.
When we understand this conflict we can do something to resolve it. Transformation begins with understanding the value stream, the work people are doing.
We illustrate the work people do in a flow diagram because the intent is to go from selection to realization quickly. Note that these are shown linearly but in fact they are done interactively and with continuous feedback. This example also does not include what heavily regulated companies (such as health equipment makers and insurance companies) or companies with hardware and software components. FLEX does apply to them; we just need to attend to these additional factors.
Figure 5: A picture of mid-scale
Be clear that we are not suggesting that there should be a flow from left to right. There is both heavy interaction and feedback required. We have not shown this in order to keep the diagram easier to understand.
That fact that the above is a common flow of software may not be surprising. Perhaps what is, however, is that 80% of organizations attempting Agile methods have pretty much the same problems. It is important to realize that most companies are organized the same way. Systems-thinking tells us that the ecosystem of a company will dictate many of the challenges it experiences. Understanding these challenges is an important start in seeing how they can be properly addressed.
Considering the value stream provides key insights
Value stream mapping is the best way to learn what is being done in your organization. We have seen many people in the same organization have different understandings of what is going on. A value stream map enables everyone to get on the same page. A general sense of an organization’s workflow is critical to see what is happening.
However, once one considers that our efforts are on realizing value (the flow from left to right in figures 2 and 3) and not on managing each group for local optimization, it becomes clear what the root causes of many of our challenges include:
By attending to our value stream and the challenges we incur, we can see where we need to put our attention.
