Labor, raw material, and capital productivity are easy concepts to understand.  For example, labor productivity is the ratio of the products delivered per unit of effort.  Increasing the efficiency of labor will either increase the amount of product delivered or reduce the amount of labor needed.  Raw material or capital productivity follow the same pattern. The issue is that while labor, raw materials, and capital explain a lot of the variation in productivity, they do not explain it all. And in software product development other factors often contribute significantly to productivity improvement. Total factor productivity (TFP) is not a simple ratio of output to input, but rather is a measure that captures everything that is not captured as labor, capital or material productivity. Factors included in total factor productivity include attributes such as changes in general knowledge, the use of particular organizational structures, management techniques, or returns on scale. The components in TFP are often the sources of productivity changes in software development.  (more…)

Productivity is a classic economic metric that measures the process of creating goods and services.  Productivity is the ratio of the amount of output from a team or organization per unit of input. Conceptually productivity is a simple metric. In order to calculate the metric, you would simply sum up the number of units of item produced and divide it by the amount “stuff” needed to make those units.  For example, if a drain cleaning organization of three people cleans 50 drains per month, their labor productivity per month would be 50/3 = 16.6 drains per person. The metric is a sign of how efficiently a team or organization has organized and managed the piece of work being measured. There are four types of productivity.  Each type of productivity focuses on a different part of the supply chain needed to deliver a product or a service.  The four types are: (more…)
