The Bathtub Curve

The defining framework of reliability engineering

Every product passes through three distinct phases of failure behaviour. Understanding the Bathtub Curve is the starting point for every reliability decision — and a core topic in both the ASQ CRE and CMRP exams.

Phase 1
Infant Mortality
Decreasing failure rate
Early failures caused by manufacturing defects, poor design, or installation errors. Failure rate is high at first and drops as weak units are eliminated.
ESS · Burn-in · HASS
Phase 2
Useful Life
Constant failure rate
Random failures during normal operation. The failure rate is essentially constant — this is where the Exponential Distribution applies and MTBF calculations are made.
MTBF · Exponential Distribution
Phase 3
Wear-Out
Increasing failure rate
Failures increase as components age and degrade. Preventive maintenance and replacement strategies are used to manage this phase and extend system life.
Weibull Distribution · PM

What you'll learn

Practical reliability skills — without heavy statistics

Define reliability as quality over time — and understand how design quality, manufacturing, and environmental factors cause products to fail
Calculate MTBF and MTTF for repairable and non-repairable products, and determine system availability using MTTR
Understand the Bathtub Curve in depth — the three failure phases, the hazard function, and what each phase means for maintenance and design decisions
Handle censored data correctly — understand right, left, and interval censoring, and use Weibull-based parametric methods (via Minitab) to estimate MTTF
Apply reliability testing methods: ALT, HALT, HASS, ESS, and Burn-in — distinguishing quantitative from qualitative tests and knowing when to use each
Build and analyse Reliability Block Diagrams — calculate system reliability for serial and parallel configurations with hot, standby, and k-out-of-m redundancy
Use the Exponential Distribution to calculate reliability during the constant failure phase — applying R(t) = e−λt with practical, worked examples
Build the foundation for ASQ CRE or CMRP certification — covering the core reliability concepts tested in both exams

Exponential Distribution

5 lessons · 21 min
  • Why the Exponential Distribution applies in the constant failure phase

FAQ

Common questions

Do I need an engineering degree or statistics background?
No. The course is designed for professionals who want to understand reliability engineering without heavy mathematical burden. Concepts like the Exponential Distribution are introduced with practical worked examples and minimal formula complexity. The only requirement is an interest in the subject — no prior reliability or statistics knowledge is assumed.
Is this course useful for the ASQ CRE (Certified Reliability Engineer) exam?
Yes. This course covers the foundational reliability concepts that appear in the ASQ CRE Body of Knowledge — including reliability definitions, MTBF/MTTF, failure distributions, the Bathtub Curve, reliability testing, and Reliability Block Diagrams. It is designed as a strong starting point for CRE candidates, covering the core principles before moving into more advanced statistical content.
Is the course also relevant for the CMRP exam?
Yes. The CMRP (Certified Maintenance and Reliability Professional) exam covers reliability fundamentals including failure patterns, MTBF, availability, and reliability-centred maintenance. This course provides the foundational reliability knowledge that underpins much of the CMRP content.
How many PMI PDUs and SHRM PDCs does this course provide?
The course provides 2.5 pre-approved PMI PDUs and 2.5 SHRM PDCs. Quality Gurus Inc. is a PMI Authorized Training Partner (ATP #6034) and an official SHRM Recertification Partner. Instructions for claiming your credentials are included inside the course.
Is this course accredited?
Yes. This course is accredited by The CPD Group (UK) — Provider #784310, Accreditation #1016215 — and qualifies for 3.0 CPD hours. A Quality Gurus Inc. verified digital certificate is issued on course completion.
What software do I need for the censored data section?
The censored data section includes a demonstration using Minitab to estimate MTTF using Weibull-based parametric methods. You do not need a Minitab licence to follow the course — the demonstration shows the approach and interpretation. The rest of the course requires no specialist software.
How long will it take to complete the course?
The course contains 2 hours and 43 minutes of video content across 34 lessons. Most students complete it in 2–3 study sessions. You have 365 days of full access, so you can work through it at your own pace and revisit sections as needed.
