Maintenance System to Achieve OEE Above 85%
The concept of improving Overall Equipment Effectiveness
(OEE) can be driven through two main activities: maintenance
activities and improvement activities, as illustrated in
Figure 2. This framework can be used to evaluate whether
current organizational practices are sufficiently effective. If gaps
are identified, organizations should assess which activities are
necessary and aligned with their operational context, and then
develop systematic action plans to continuously and sustainably
improve machine OEE.

5 Strategic Machine Maintenance Practices for
High-Performing Production & Maintenance Teams
Based on the above concept, five key practices can be identified.
These must be properly implemented and involve both production
and maintenance functions:
1) Normal Operation: Production operators must be able ภาพที่่� 3 การเปร่ยบำเที่่ยบำลักษณะของการบำำารุงรักษาเช่ิงป้องกัน

maintenance staff may train operators to perform basic Operational difficulties—such as challenges in cleaning,
troubleshooting to minimize downtime. If operators cannot inspection, lubrication, or accessing machine components—
can also hinder effective maintenance. Therefore, production
and maintenance teams should collaborate to implement
Kaizen initiatives, improving both operational methods
and maintenance practices to be simpler, safer, and more
efficient. These efforts will contribute to continuous OEE
improvement.
Achieving higher productivity in manufacturing should
begin with accurate measurement of machine performance
that reflects actual operating conditions. organizations should
then implement both maintenance activities and improvement
activities appropriately, with strong collaboration between
production operators and maintenance personnel. Such an
approach will support machines in achieving the targeted
level of Overall Equipment Effectiveness (OEE) and enhance
overall operational performance.
