Object-Oriented (OO) methodology to use the concept like encapsulation, inheritance, polymorphism, and message passing demands metrics that are different from structured methodology. There are many studies for OO software metrics such as program complexity or design metrics. But the metrics for the analysis class need to decrease the complexity in the analysis phase so that greatly reduce the effort and the cost of system development. In this paper, we propose new metrics to measure the complexity of analysis classes which draw out in the analysis phase based on Unified Process. By the collaboration complexity, is denoted by CC, we mean the maximum number of the collaborations can be achieved with each of the collaborator and detennine the potential complexity. And the interface complexity, is denoted by IC, shows the difficulty related to understand the interface of collaborators each other. We prove mathematically that the suggested metrics satisfy OO characteristics such as class size and inheritance. And we verify it theoretically for Weyuker' s nine properties. Moreover, we show the computation results for analysis classes of the system which automatically respond to questions of the it's user using the text mining technique. As we compared CC and IC to CBO and WMC, the complexity can be represented by CC and IC more than CBO and WMC. We expect to develop the cost-effective OO software by reviewing the complexity of analysis classes in the first stage of SDLC (Software Development Life Cycle).

Nowadays there are gradually the importance issues of embedded software for productivity as the fusion and complexity of industry. Especially, people are recognizing the importance of reliability within the embedded software systems(e.g. weapons and medical equipments, etc.). It makes currently mention of software reliability on ISO/IEC 9126, 12119, etc.. However, it is insufficient for the embedded software area in spite of being mentioned the generic software. To do this, we suggest our embedded software reliability assessment through extracting the embedded software meaurement items from reliability assessment items of ISO/IEC 9126, 12119 series.
