Uncertainty explicit assessment of off-the-shelf software: A Bayesian approach

Investigating ERP systems procurement practice: Hong Kong and Australian experiences

“…In this regard, the formulation of evaluation criteria and the corresponding assessment methods developed for commercial-off-the-shelf (COTS) components may be taken into consideration and adapted for use at this stage [3,7,17,28,29,37]. …”

“…A relatively ''long" list (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) of package vendors and a detailed list of functional and technical requirements for the new system are then prepared. The detailed requirements are prioritized and classified into categories such as mandatory, desirable, and optional.…”

“…They then develop a COTS product evaluation process, which helps an organization obtain valid quantitative indicators to assess product quality and suitability prior to purchase. Gashi et al [17] take into account the uncertainty and incompleteness of the knowledge of COTS products and other aspects (for example, vendor's credentials), and introduce a Bayesian approach for assessing COTS components. However, neither Lawlies et al [29] nor Gashi et al [17] have considered ERP evaluation, and whether their methods are applicable to ERP adoption projects remains to be confirmed.…”
