Metrics based OSS system status overall assessment


This article is devoted to the problem of design OSS system status common estimation on the metrics base. The estimation is formed on the base of ITILs metrics. For every metrics with a help of experts is made an estimation in the form of the mark. This mark shows how closing the IT-service quality to the service focus mark. Additionally, there is a marks for estimate of experts assent opinion forming with a modificated hierarchy method analysis. Finally, to find a OSS system status common estimation this metrics are coupled with a matrix and common estimation are design as a part of base project, where the base is conform to a maximum mark. A practical example is designed.
Key words: OSS, metrics, ITIL, IT-service.
