The quality of the software can be measured by its return on investment. Factors which may affect the return on investment (ROI) is the tangible factors (such as the cost) dan intangible factors (such as the impact of software to the users or stakeholder). The factor of the software itself are assessed through reviewing, testing, process audit, and performance of software. This paper discusses the consideration of return on investment (ROI) assessment criteria derived from the software and its users. These criteria indicate that the approach may support a rational consideration of all relevant criteria when evaluating software, and shows examples of actual return on investment models. Conducted an analysis of the assessment criteria that affect the return on investment if these criteria have a disproportionate effort that resulted in a return on investment of a software decreased.

This article examines the relationship between a firm's strength in product development and its optimal scope. Firms with product development strength have two options: They can leverage it in horizontally related markets, and they can reach into the supply chain to take full advantage of it. The question is how this should be done. One possibility is for the firm to expand its scope, and another is to manage the linkage through contracts. On the basis of the adjustment cost theory of the firm, the author argues that the former solution is more appropriate when product development is fast-paced. This study tests the argument in a sample of several thousand firms and reports four tests. For both types of expansion, the author examines the incidence and the productivity of increased scope. The author uses several measures and finds results that are consistent with the theory.
