The dynamics of the processes taking place in an environment, which is rendered in the

altered perception of the character of this environment, induces a need to find answers to

the following questions: (1) How do managers perceive an environment in the dimensions of

stability/ changeability and friendliness/unfriendliness? (2) Is there a correlation between

the stability/changeability and friendliness/unfriendliness of an environment, i.e. if an environment

is more stable, is it perceived as more friendly, and if an environment is more

changeable is it perceived as unfriendly? (3) Does environmental stability/changeability as

well as friendliness/unfriendliness exert any influence on organizational effectiveness? In

an attempt to answer the above quoted questions, the article’s objective has been defined

as a discussion on the interdependencies perceived by managers between an environment’s

dimensions of stability/changeability and friendliness/unfriendliness (analysed in terms of

institutional categories) and the organizational effectiveness of Polish enterprises.

The managers evaluated the legal environment as the least stable. In their opinion, that

milieu was also more intimidating than friendly. Concurrently, a technological environment

was perceived by the respondents as the most stable and favourable. The results of the

effected research allow forming a conclusion concerning the existing correlation between

the friendliness and stability of particular categories of an environment, at the same time

pointing out to the occurrence of correlations between stability/changeability and friendliness/

unfriendliness of some categories of an environment and the organizational effectiveness

of the examined enterprises.

Management and Production Engineering Review (MPER) is a peer-refereed, international, multidisciplinary journal covering a broad spectrum of topics in production engineering and management. Production engineering is a currently developing stream of science encompassing planning, design, implementation and management of production and logistic systems. Orientation towards human resources factor differentiates production engineering from other technical disciplines. The journal aims to advance the theoretical and applied knowledge of this rapidly evolving field, with a special focus on production management, organisation of production processes, management of production knowledge, computer integrated management of production flow, enterprise effectiveness, maintainability and sustainable manufacturing, productivity and organisation, forecasting, modelling and simulation, decision making systems, project management, innovation management and technology transfer, quality engineering and safety at work, supply chain optimization and logistics. Management and Production Engineering Review is published under the auspices of the Polish Academy of Sciences Committee on Production Engineering and Polish Association for Production Management. The main purpose of Management and Production Engineering Review is to publish the results of cutting-edge research advancing the concepts, theories and implementation of novel solutions in modern manufacturing. Papers presenting original research results related to production engineering and management education are also welcomed. We welcome original papers written in English. The Journal also publishes technical briefs, discussions of previously published papers, book reviews, and editorials. Letters to the Editor-in-Chief are highly encouraged.
