Abstract.One resource indispensable for securing the capacity to carry out processes is an environment made up of social, psychological, physical and other factors. The nature of such environmental factors and the manner in which they affect the capacity to carry out processes and produce goods and/or services translates into a company's ability to meet the expectations of stakeholders, including the organization's customers. In order to define the preconditions for the efficient implementation of processes, it is necessary, among others, to ascertain the manner in which such preconditions influence process operation. One of the criteria that should be applied in such an assessment is the impact of working environment factors (temperature, lighting, noise, toxicity, dust, electromagnetic fields) on the ability to carry out work processes effectively. The paper accounts for working environment factors seen as parameters for the assessment of processes and as criteria for ascertaining the ability to perform work. The impact of the working environment on the capacity to conduct processes was assessed by means of a relationship diagram.
