An increase in internet threats forces organizations to integrate information security system into their fundamental systems. Developers who work in this area should focus on both functionality and quality aspects because a malfunctioned system can endanger organization’s most critical information. Although several approaches to solve a resource distribution problem have been proposed, little attention has been given to the problem which is a combination of resource distribution, tradeoff and multi-criteria optimization. This paper proposes a systematic approach for project leaders to efficiently distribute their limited resource to gain an optimum quality software product by using QFD (Quality Function Deployment) to prioritize quality factors and DF (Desirability Function) to optimize the product quality.
