About Failure Curve Analysis
Failure Curve Analysis in lean manufacturing is a technique used to understand the lifecycle and reliability of equipment by analyzing failure patterns over time. This analysis helps in predicting future failures, planning maintenance activities, and improving overall equipment effectiveness.
There are six types of curves:
| Curve Types in FCA |
Type A | Bathtub
A curve that represents when the equipment is new, followed by a low level of random failures and then a sharp increase in failures at the end of its life. |
Type B | Wear Out
A curve that represents a low level of random failures, followed by a steep increase in failures at the end of its life. |
Type C | Fatigue
A curve that is characterized by a gradually increasing level of failures over the course of equipment’s life. |
Type D | Initial Break-in Period
A curve that represents the initial break-in curve and starts off with a very low level of failure followed by a sharp rise to a constant level. |
Type E | Random
A curve that represents a consistent level of random failures over the life of the equipment with no pronounced increase or decrease related to the life of the equipment |
Type F | Infant Mortality
A curve that represents a high initial failure rate followed by a random level of failures. |

Useful Facts!
When a new section is added it appears under the previous section; in this case Description of Repairs Section.
Step 2
Expand the section by clicking anywhere in the section field, or on the arrow on the right side.
The arrow can also be used to collapse the section.
Step 3
From the Drop-down menu select the curve that you wish to add to the kaizen phase.
Refer the table above or the descriptions in the curve options.
Step 4
Click on Save when finished.
Collapse the section post saving your selection.
Congratulations! We have successfully learned about the Failure Curve Analysis Section inside Kaizen!
Great work! We have finally concluded the all the 17 sections inside Kaizen!
You deserve a break after all that information!
Post that we can continue the rest of the learning of the kaizen system!
