Complacency
Allowing yesterday’s adequacy to excuse today’s lack of examination.
Unwarranted satisfaction with one's adequacy that weakens needed attention or improvement.
Imagine this: A system that once worked well stops receiving the attention its continuing adequacy requires.

How the pattern works
The old photograph remains beautifully tidy while the living system grows around the phone. Complacency treats an earlier satisfactory condition as a continuing reason not to examine what has changed.
An executive may inherit capable people and reliable routines, or have helped establish them. That success becomes a source of unwarranted assurance when it removes the perceived need for attention. Small changes accumulate without appearing individually decisive. The organization still describes its arrangements through the account that was true when they were established.
What it costs the work
An undertaking can lose access to warnings already present in ordinary experience. Staff may keep compensating for the drift, allowing the official picture to remain reassuring. By the time the difference becomes conspicuous, correction may require more than the modest attention that would have kept the system useful.
A distinction worth keeping
Satisfaction with good work and confidence in established capability are not vices by themselves. Complacency weakens needed attention through unwarranted adequacy. Arrogance asserts excessive importance or judgment; Complacency need not compare itself with anyone. Rigidity can resist an acknowledged reason to change, whereas Complacency may not feel an examination is necessary.
What a useful response can change
Ask what evidence supports the current assurance, rather than which achievement originally earned it. A useful review can be modest and specific to changes that matter.
Notice where people have begun compensating for the arrangement. Their ingenuity can conceal a growing mismatch rather than prove that the original system remains adequate.
Treat a discovered limitation as information for care, not a demand for impossible perfection. The aim is to keep the undertaking answerable to present conditions.
Questions for reflection
- Which assurance depends most heavily on a story about our past?
- What are people now doing privately to keep the official arrangement looking workable?
Other perspectives
Some are so taken up with routine as to be inaccessible to new facts and problems.
John Dewey · How We Think · Read the source
Dewey identifies a routine that closes attention to new facts. An established practice is useful only while the organization can still receive observations it did not anticipate.
I was surpris’d to find myself so much fuller of faults than I had imagined; but I had the satisfaction of seeing them diminish.

Franklin’s autobiographical observation concerns the difference between self-image and examination. It does not introduce vice tracking here or establish completion or performance conclusions from a Workbook grid.
