@Stray__Cat, a BI expert in Italy who I follow on Twitter, published a blog post called Measures, Metrics and KPIs. As you know, anything KPI related piques my interest. This post aimed to clarifying these terms, and as we've got a similar initiative underway, I thought I'd jump into the discussion with my own thoughts... I encourage you to read his thoughts as well, and let us both know what you think.
Definition: A measure is an agreed upon concept of quantification. It's a standard, which when "measurements" or "values" are associated, allows for a common language and a basis for comparison.
Example: Speed expressed in km/h, or temperature expressed in ºC, or beer as a pint.
Definition: IMHO, a measure and a metric are the same thing. And according to the Oxford dictionary, the word measure is derived from the Latin "metiri". Having said that however, in speaking with a number of my colleagues, there seems to be a subtle difference in that the term metric has more of a goal or performance nuance to it, as opposed to the fundamental or unit specific term measure.
Example: Speed limit of 50 km/h, or the boiling temperature of 100 ºC, or ordering half a pint of beer.
Definition: KPIs are measurable industry, department or task relevant performance metrics that are evaluated over a specified time period, and compared against acceptable norms, past performance or targets.
Example: Currently we are driving at 60 km/h (10 km/h higher than the posted speed limit of 50 km/h), or the average water temperature over the past week was 95 ºC (5 ºC lower than the target temperature of 100 ºC), or average pints per patron per visit at our pub this month is 1.6 (compared to the local pub average of 1.4ppv and last month's average of 1.3ppv).
The next step is figuring out what to do with all this information. For businesses seeking to consolidate and clarify frequently changing measures, metrics, and KPIs, a web and mobile accessible dashboard makes sense. Not only does it automatically retrieve your data, it also presents that data using effective visuals. The best part is that this information is accessible on any smart phone, tablet, or Internet-browser.
