What is the different between generic products and customize products?

A generic software product is made according to future updates. For custom software, changes are done when the customer needs them. Customer’s requirement can be fulfilled whenever the customer asks for it. Custom software is made according to the time, the budget and the needs defined by the client.

How is software reliability calculated?

Product Reliability For measuring the failure rate of a software product, we can have N installations of the software under observation. If the total number of failures in all the N installations in a time period T is F, then the best estimate for the failure rate of the software is [18] λ = F / (N * T) .

What is software reliability and availability?

Using availability and reliability The measurement of Availability is driven by time loss whereas the measurement of Reliability is driven by the frequency and impact of failures. Mathematically, the Availability of a system can be treated as a function of its Reliability.
