Thirdly, human behaviour systems comprise varying numbers of people interacting with each other and processes, procedures and equipment in their workplace. The nature of these interrelationships and interactions has a profound effect on the way overall system operates. Unlike a mechanical device, the overall result of these relationships means that the behaviour of the system is unpredictable. Again, systems thinking looks at ways of taking these relationships into consideration.
Overall, we can therefore see that a systems-based approach to looking at what happens in the workplace requires us to look at boundaries, perspectives and relationships, and this is the basis of the B-P-R model. I provide consultancy and training services on how to use the model to consider performance problems, and more detailed information is found in my forthcoming book, "Performance and evaluation: a systems thinking approach", to be published in late 2016.
