Abstract

Purpose

The purpose of this paper is to design a model to outline the structure of communities of practice (CoPs) corresponding to organizational context.

Design/methodology/approach

This research utilizes both descriptive and prescriptive approaches, as the authors are looking for a comprehensive relational model to deal with the problem of selecting suitable CoPs concerning organizational context. Thus, this study applies interviewing and fuzzy Delphi methods to explore the model.

Findings

The work provides a new and comprehensive relational model of CoPs and organizational variables affecting CoPs structure. In this model, three basic concepts of the literature were developed. First, the components concerning types of CoPs were identified and then the organizational variables related to CoPs were determined. Finally, the authors extracted the relationships between the organizational variables and the components of CoPs.

Practical implications

From a practical perspective, the relationships among the components concerning types of CoPs and the organizational variables may provide a model which can effectively guide firms how to promote, design and manage CoPs within organizational contexts.

Originality/value

The results of this study contribute to CoPs literature in terms of identification of two variables (CoPs components and organizational variables) to produce a matrix for the construction of a holistic CoPs model. The significant finding of this research is the guidance it provides for designing a relational model involving relations between organizational variables and CoPs components.

Abstract

Purpose

The aim of this Education Briefing is to comment on the problematic issues that sometimes arise when using the internal rate of return (IRR) and/or the net present value (NPV) as a measure of expected investment performance. The briefing looks at the sometimes conflicting signposts that each benchmark presents and highlights ways that decision-makers can overcome or mitigate the effects of those problematic issues.

Design/methodology/approach

After a short review of the IRR and NPV techniques, this Education Briefing provides numerous examples of problematic issues that arise with certain cash flow profiles and suggests how to address them.

Findings

Both the IRR and NPV provide simple benchmarks that can mislead the decision-maker who is not familiar with the nuances of both techniques.

Practical implications

This review should heighten the reader’s ability to spot characteristics of proposed investments that may signal that a quick decision based on performance metrics may lead to disappointing results. These characteristics include: scale effects, unusual cash flow patterns and/or investments with dissimilar expected lives. Mutually exclusive investments merit special attention.

Originality/value

This is a review of existing performance measurement models.
