Risk Perception of Enginieers on Software Develpoment.

Abstract

It is important to manage risks in software development. To manage the risks, risks which may occur in the project are identified by some methods such as brainstorming, and risk treatment plans are made based on that. However, risk recognition is considered to include biases, and it may affect correctness of identification of the risks. To recognize the risks precisely, we clarified risk recognition of software developers. Our study identified the risk recognition quantitatively using the questionnaires based on Slovic's study. The answers of questionnaires are compressed to two factors (dread and unknown). We analyzed answer of questionnaires collected from 69 subjects (most of them are software developer). As a result, strength of “dread”and“unknown”factors were different among risks, when experience of risk was different among subjects, and the difference affected the recognition to severity of each risk.
