Software Reliability and Safety Services

Please go to our new website at http://www.missionreadysoftware.com/services

Software reliability engineering encompasses both quantitative and qualitative analyses and methods.  The quantitative methods are employed to ensure that the system reliability objectives of software intensive systems are met.  Ideally the quantitative methods are used as early as possible to ensure that risks that effect reliability are mitigated in time to ensure an on time delivery.  The qualitative methods are employed to ensure that the most likely failure modes are identified and mitigated in time to ensure an on time delivery.  The cost of the services vary depending on the size and complexity of the software project and the location of the services to be performed.

All services are conducted in accordance with recognized industry standards as shown in the below table.
