Metrics for measuring the consistencies of requirements with objectives and constraints

Requirements engineering (RE) is essential to succeed in software projects. That is, it is important to elicit sound requirements for proper performing of RE. If some requirements are inconsistent with a given objectives and constraints, these requirements may hinder the performance of RE. For this reason, it is necessary to pre-check the consistency of requirements. We propose the metrics for evaluating requirements by considering given objectives and constraints. Our metrics are validated by two sample scenarios: “Payroll and Roster Planning of Hospital” and “Noise Source Location System.” At the result, we expect that these metrics would be helpful when selecting a set of consistent requirements.

A Study on Techniques for Measuring Requirement Suitability Considering Project Objectives and Constraints

The suitability of requirements that are developed and changed is a key factor to make a success of project. The key elements of requirement suitability are the objectives and constraints which are decided by scope. To ensure that requirements have suitability, our study proposes the techniques for measuring requirement suitability considering objectives, constraints and requirements. To calculate requirement suitability points, which are quantities calculated by these techniques, we develop indicators and metrics based on relationship among objectives, constraints and requirements, and propose expressions to quantify our indicators using MCDM (Multi Criteria Decision Making) techniques. An interpretation and usage of our techniques are described by statistical analysis.

A Model for Measuring the R&D Projects Similarity Using Patent Information

It is important to analyze the similarity of R&D projects for efficient investments of governments budgets. In this study, we represent the methods of analyzing the similarity between R&D projects using patent information. For this, we propose a model for similarity measurement based on the set theories and probability theory.

An Approach to Requirements Refinement Based on Users’ Opinions

A software has to embrace the users’ opinions. It is very important to succeed the software today. However, the users’ opinions might not be proper for directly accept into requirements. We propose the approach for requirements refinement based on users’ opinion. Our approach is consisted in a form of writing requirements, keyword analysis, a graph/hierarchy of relationship of keyword/requirements. Our approach would provide a foundation of User Centric Requirements Engineering and its automation.
