We have completed and released our HALT/AFR Calculator for public use. And based on feedback from our customers, we have made recent modifications to the calculator so please take another look.

It can be used to calculate Actual Failure Rate (AFR) from HALT Data. The model was created by a distinguished member of the reliability community, Harry McLean and is being offered exclusively through Ops A La Carte.

How many of us have wanted to use the HALT data to estimate Actual Failure Rate (AFR)? The common response is that "it cannot be done." In fact, it is possible but what you need is a good model and good data to back the model. This is exactly what Harry did. See the following write-up HALT Calculator for more information on the calculator and how to use.

We will run calculations for customers at a cost of $500 per calculation. Or for customers that perform HALT and a Reliability Prediction with our company, we are offering the calculation for free.

Harry presented this calculator at the annual ASTR Conference. Download a copy at HALT_Calculator_Presentation.

Below is a picture of the calculator. The green area is customer input and the pink area is model output.

Note that the calculator is a model based on data, and with all data-driven models, the more data, the better. So if you have any HALT data you can share with us, we will give you free access to the model. Here is what we need:
1) HALT results (final HALT values after corrective actions have been verified)
2) Estimated MTBF
3) Actual field failure (AFR)
4) Type of product; i.e., internet server, etc.
5) Your contact info in case of questions
