Rome Laboratory Software Reliability Prediction Model
The Rome Laboratory TR-92-52 Software Reliability Measurement model correlates many
software development practices to defect density. You check the practices you have in
place and Frestimate computes the number of predicted defects based on those practices.
These practices are based on common practices by defense contractors.
However, this model is still very useful for companies that are developing commercial
software. One of the key benefits of this model is that it is a multiplicative
model. That means that you can predict a baseline defect density using any other
model and then use the "factors" to calibrate that baseline.
- Software managers make use of this by doing tradeoff analyses to determine which
practices will result in lower defects in the future as well as identifying practices that
may not be reducing defects as well as others.
- Software test managers use this model to gauge the testing effort required to meet a
specific quality objective.
- Reliability engineers use this model to predict system reliability.
This module contains
- A multi parameter model developed by Rome Laboratory for predicting defects, defect
density, MTTF, failure rate, MTTCF, critical failure rate, reliability,
availability
- Wizards for collecting prediction inputs
- Technical help files for the Rome Labs model
Key Benefits
- Geared towards practices employed by larger defense and aerospace companies
- Can be tailored to whatever historical or industry data you have available
- Allows for tradeoff's and identification of key practices
- Versatile for use by software managers, reliability engineers and testing managers
