Practical guides to the methods behind the software — worked examples included, no sign-up required.
What Weibull analysis is, what the shape and scale parameters actually tell you, how fitting works (with a worked example), how censored data changes everything, and how the results turn into maintenance decisions.
Read the guide →B10 life is the time by which 10% of a population has failed. Here's the exact Weibull formula, a worked calculation, how B10 relates to bearing L10, and why it beats MTBF for setting intervals.
Read the guide →Most reliability datasets are dominated by units that haven't failed. Ignore those suspensions and your life estimates come out 2× wrong or worse. Here's what censoring is, with a worked example of the damage.
Read the guide →A complete, honest walkthrough of Weibull analysis in Excel using median rank regression — worked example included — and the exact point where Excel stops being the right tool.
Read the guide →MTBF is for repairable systems, MTTF for non-repairable — that's the textbook line. Here's the full story: exact definitions, how to compute each from real data, and the ways both numbers routinely deceive.
Read the guide →A complete reliability centred maintenance example — functions, functional failures, failure modes, consequences, and task selection for a cooling-water pump — with the worksheet filled in and the reasoning shown.
