Although the PMESII-PT has been originally used by the military in the United States as a strategic tool, it has since then been gaining increasing popularity within the business world. PMESII-PT is used to examine and assess the external environment when the amount of operational information is vast. The tool is compromised by eight inter-connected operational variables which are Political, Military, Economic, Social, Information, Infrastructure, Physical Environment, and Time. Each one of them is further discussed below:

1. Political

The political variable looks into the political power, structure, and hierarchy within the operational environment. This factor is all about the role of government within the economy, with some trending issues being the tax policy, the trade restrictions, the foreign trade policy, and the overall political stability.

2. Military

The military variable shifts focus on the military environment and especially concerning factors like available resources, war zones, military equipment and training, leadership and so on. When this model is applied within a business landscape, this factor may be used for the competitive analysis.

3. Economic

Following, the economic variable examines key areas that concern the economic growth or development of a country or business in question. Some points that need to be addressed are international trade, distribution, and consumption of resources, inflation, consumer income, and so on.

4. Social

The social variable of the PMESII-PT  is responsible for inspecting the shared beliefs, attitudes and behaviors of the population. Here, we need to uncover the cultural and religious background of the different social groups within a society and evaluate how that can impact the organization’s operational processes and procedures.  Norms, population growth, age distribution, religious beliefs, career attitudes, political influences, and subconscious beliefs are all factors that need to be looked into.

5. Information

This variable is concerned with the characteristics of individuals or groups that are responsible for handling information within the operational environment. Nowadays, media plays a big role here and its impact on the public opinion must be taken into account when decisions in regards to this variable are being made.

6. Infrastructure

 The infrastructure variable inspects the background systems and facilities in place, supporting the society or the organization in question. Within a societal context, the infrastructure variable entails communication systems, water, electricity, methods of transportation, education systems, and similar facilities. Within an organizational context, this variable encapsulates technological capabilities, R&D and IT facilities.

7. Physical Environment

As its name implies, the physical environment is concerned within physical factors such as the climate, the landscapes, the biosphere and other environmental characteristics that may have an impact in the operational environment. Knowing what to expect can provide a useful advantage over unprepared competitors.

8. Time

The last factor of the PMESII-PT is time and this variable looks into everything that has to do with timings. This might include the timing of decisions, the speed of operations, the duration of various operational processes, as well as the planning of all the above.
