TL;DR
When asked to provide metrics to assess “how well” an Agile transformation is going, re-frame the discussion around measuring changes in the impact the IT organization is having (or not) on it’s Business environment, and define a small set of “fitness for purpose” metrics.
The Inevitable Question about Agile Transformation Metrics
Sooner or later, as an IT organization embarks on a transformation towards Agile mindset and practices, someone will be asked to provide “hard evidence” that the effort is paying off, and the conclusion will be that metrics is the vehicle to satisfy that request. What are your Agile transformation metrics?
It’s been my experience that this request usually leads to a discussion about measuring the specific Agile initiatives the IT organization has launched. In organizations where the emphasis has been around engineering disciplines, such metrics might be things like unit test code coverage, or integration build times. If the focus was around teams and process, then counting number of teams “converted” to Scrum, or people sent to Scrum Master training may appear as the choice.
While those measurement might be useful indicators in some context, they have two problems. First, they are akin to measuring the performance of the car engine without looking outside the window; the engine might be performing well, but if the car doesn’t have the wheels attached, we’re going nowhere. More importantly, though, these figures are usually meaningless for Business stakeholders, who are the ones usually asking for them in the first place. Agile transformation metrics need to be meaningful to the Business.
Re-framing the Agile Transformation Metrics Question
Agile transformation efforts can be very costly exercises, therefore it is legitimate to ask about the results of such endeavour. The important thing to realize, though, is that this question is really equivalent to another question: “is the IT organization improving its impact on its Business environment.” Another way to put it is, borrowing from the terminology used by the Kanban community: “is the IT organization becoming more and more fit for purpose?” Answering this question, of course, requires a clear understanding of what is that the Business expects from its interactions with IT.
The IT organization can be seen as providing various services to customers. Arguably, if IT has decided to “transform” in some way (perhaps by moving towards an Agile mindset), it’s doing so to improve its impact on those customers, so this is what needs to be measured to know “how the transformation” is going.
Some of those customers are different areas of the organization (like Finance, or HR.) But it doesn’t stop there, because the Business’ engagement with IT doesn’t have value for its own sake. Ultimately, the Business is using IT as a way to optimize its operations so that it can provide external customers with more effective products and services. Moreover, IT is these days the direct channel through which those products and services are delivered to external customers (for example, through web sites and mobile applications.) Therefore, the concept of “fitness for purpose” of the IT organization can be extended to consider the fitness for purpose of the Business respect the external customers it intends to serve.
Defining the “Agile” Transformation Metrics
Measuring “agile transformation success” really means measuring the success of the exchanges between IT and the Business, and between the Business and its external customers. Measuring the internal processes and practices that IT puts in place as part of that “transformation” is beside the point. This implies starting with a careful definition of the boundaries that delineate the exchanges to be measured. There might be more to external customer fitness for purpose than IT operations, for example, and that needs to be considered when defining Agile transformation metrics, especially if we’re later going to be drawing causation conclusions.
Defining Agile transformation metrics will be, of course, a highly contextual exercise because every business organization is different. But we can, however, draw again from the Kanban community for some general guidelines on what to look for. Their thought leaders talk about classifying metrics into 3 categories: fitness for purpose metrics, health indicators and improvement drivers. Using this framework, when talking about “agile transformation metrics” we are referring mainly to the first category, and perhaps a bit to the second. Based on those, improvement initiatives can be put in place, and perhaps driven with metrics belonging to the third category.
A fitness for purpose metric (also known as KPI) is an indicator of something a customer will care about. This is a key distinction: if the metric is not easily recognizable and meaningful for the customer, then it’s not a KPI. Another key characteristic is that a minimum threshold for its value can be defined: if the metric goes below the threshold, the Business is putting the relation with its customers at risk (perhaps they will walk away, initiate legal actions, etc.). In other words, the Business is no longer “fit for purpose”. We can then measure the effectiveness of the “agile transformation” by analyzing how KPI values over time compare to their respective thresholds. A typical KPI is delivery time, measured from the moment a customer request is accepted and committed to, until the moment it’s delivered to production. This is usually a good Agile transformation metric.
Health indicators are metrics that are inwards facing. Customers don’t really care about them (or even understand), but they indicate how a given aspect of the system is operating. The key characteristic is that they are not directly actionable; they only provide information that needs to be analyzed and put in context. As the value of a health indicator changes, we can draw some conclusions about how the system works, or explain why something is happening (or not), but it doesn’t necessarily leads to concrete action. Defect count is an example of this. Customers will certainly care about quality of the product, and we can make inferences about that quality by looking at how many defects we have, but the absolute number of defects will not necessarily make the product more or less fit for purpose. It may happen that customers consider the current quality to be “good enough”, irrespective of the number of defects.
Finally, improvement driver metrics are metrics put in place to influence behaviour towards a particular change. Their key characteristic is that they are temporary: we set a target on them and once the target is achieved, the metric is no longer necessary. The reason for this is related to the unintended behaviours that a metric might encourage in people, which may lead to locally optimizing the metric at the expense of other aspects, leading to global sub-optimization of the system. An example is unit testing code coverage: if we have determined that a given service is not fit for purpose and the cause is related to poor unit test coverage, then establishing a target for minimum coverage may influence developers to work on adding tests to reverse the situation.
