This document discusses workmanship, mutual understanding, and examples of their application. It contains the following key points: 1. Workmanship refers to Total Productive Maintenance and ISO 9001 standards which aim to improve quality through reducing rework and meeting competitive demands. 2. Mutual understanding bridges common sense and common knowledge. Common sense refers to practical judgment shared by most, while common knowledge is information known by many in a community. 3. Examples show cases where common sense, common knowledge, and mutual understanding do or do not align regarding work done, with implications for functionality, safety, or visual appeal.

1. Workmanship
& Mutual Understanding

2. Workmanship
• Total Productive Maintenance (TPM);
• One of the wasteful activitiy where waste in
maintenance occurs that Lean maintenance needs to
focus on: Rework – Having to repeat tasks, or do
additional tasks, as a result of poor workmanship.
• ISO 9001;
• To improve workmanship due to the competitive
demand for quality projects and infrastructure in the
market.

3. Mutual Understanding
• Common sense
• sound, practical judgment concerning everyday matters, or a
basic ability to perceive, understand, and judge in a manner
that is shared by nearly all people.
• Common knowledge
• is knowledge that is known by everyone or nearly everyone,
usually with reference to the community in which the term is
used.
• Mutual understanding is needed to bridge the gap
between common sense and common knowledge
