PurposeDespite the great interest in activity based costing (ABC), companies seem to be reluctant to adopt it. Our research aims at examining the rate of adoption of ABC by Greek companies that belong to all three sectors of the Greek economy, i.e. manufacturing, retail and services, as well as investigating the reasons that influence a firm's decision to change its current cost accounting system.Design/methodology/approachAn empirical survey via questionnaires was conducted during 2003 on a sample of 88 Greek leading companies and four company categories were identified in respect to their perceptions towards ABC (ABC adopters, ABC supporters, ABC deniers and ABC unawares).FindingsOur findings indicate that ABC diffusion in Greece is quite satisfactory. Furthermore, we present evidence that firms that have implemented ABC (ABC adopters) have experienced multidimensional management facilitating benefits from the system. However, the adequacy of resources was found to be the variable that is positively and statistically correlated with the majority of problems encountered during ABC implementation process. On the other hand, the companies that include ABC in their future plans (ABC supporters) seem to be familiar with the corresponding expected benefits and potential problems of its adoption. We present evidence that the possibility of future ABC adoption is related to the degree of satisfaction from the currently used cost accounting system. Companies that do not intend to adopt ABC (ABC deniers) were found to be more satisfied with their existing cost accounting system in comparison to ABC supporters. We also report the characteristics of companies that still have complete ignorance of the ABC technique (ABC unawares).Originality/valueThe paper not only proceeds in a thorough analysis of the benefits perceived in relation to ABC as they have been presented in similar research, but also moves a step further and groups these benefits into distinct categories as well as ranks them in order of perceived importance. Furthermore, it analyzes the basic characteristics of the firms that have complete ignorance of ABC (ABC unawares), a group that is rarely met in ABC research papers.

PurposeThis paper aims to explore the relationships among cost accounting systems structure and information quality properties through an integrated framework of cost system design and use.Design/methodology/approachIn the framework, cost accounting systems structure is defined in terms of the level of detailed information existence, the cost disaggregation according to behaviour, the scope of variances calculation and the frequency of cost information provision. Cost information quality expresses its perceived usefulness by the users in terms of relevance, accuracy, timeliness, usability, compatibility with their needs, up‐to‐datedness, reliability and thoroughness for decision‐making purposes. In order to investigate the existing relationships, data were gathered from 119 leading Greek manufacturing companies via a questionnaire survey.FindingsThe empirical findings indicate that the majority of cost accounting systems structure characteristics exert a statistically significant positive influence on cost information quality dimensions. Only the systems' ability to disaggregate costs according to behaviour and their capability to generate customized to user specifications reports were not found to be statistically significantly associated with information quality.Research limitations/implicationsThe authors believe that their conclusions have important implications for researchers and professionals with respect to cost systems design as well as cost systems evaluation.Originality/valueThe innovation of the study lies in the development of an integrated framework that encompasses both cost systems structure characteristics and cost information effectiveness features.
