[Abstract]: With increasing interest by the software development community in software process improvement (SPI), it is vital that SPI programs are evaluated and the reports of lessons learned disseminated. This paper presents an evaluation of a program in which low-rigour, one-day SPI assessments were offered at no cost to 22 small Australian software development firms. The assessment model was based on ISO/IEC 15504 (SPICE). About twelve months after the assessment, the firms were contacted to arrange a follow-up meeting to determine the extent to which they had implemented the recommendations from the assessment.
Comparison of the process capability levels at the time of assessment and the follow-up meetings revealed that the process improvement program was effective in improving the process capability of many of these small software development firms. Analysis of the assessment and follow-up reports explored important issues relating to SPI: elapsed time from assessment to follow-up meeting, the need for mentoring, the readiness of firms for SPI, the role of the owner/manager, the advice provided by the
assessors, and the need to record costs and benefits. Based on a meta-analysis of the program and its outcomes, advice and recommendations are provided to small firms and assessors. As well as providing validation of the assessment model and method, the outcomes from this research have the potential to better equip practitioners and consultants to undertake software process improvement, hence increasing the success of small software development firms in domestic and global markets
