To implement successful business process re-engineering (BPR) initiatives, several capabilities have been identified. Required capabilities before and during implementing of BPR projects have been introduced for achieving success. The literature has suggested various approaches to assessing readiness and implementation of BPR projects. However, lack of a practical measurement method is evident. Therefore, in this paper, a practical measurement tool for requiring capabilities is proposed to enhance the chances for successful implementation of BPR by mapping these capabilities on steps of BPR projects. In addition, the relations between these capabilities and BPR success barriers are identified. This tool includes a generic questionnaire that can be helpful for self-assessment of readiness based on the desired organisational capabilities (DOCs) in BPR efforts. In the questionnaire proposed in this paper, various indicators have been identified for assessing readiness in BPR implementation. These indicators include 21 categories based on DOCs. This report indicates the importance of each DOC in various steps and the influence of DOCs on different barriers of success. We report the results of a survey based on the questionnaire, which was conducted in four Iranian organisations. Based on the results gathered from this examination, the study offers several guidelines for increasing the points of success and decreasing the points of failure and, hence, increasing the rate of success before and during implementation.
