Field evaluations indicate that data integration with ERP systems remains suboptimal, triggering human error and weakening production data accuracy.
JAKARTA, JurnalPost.com — Digitalizing production lines through Computer Control Machining Systems (CCMS) is often promoted as the path to manufacturing efficiency and accuracy. However, conditions on the ground reveal a more complex story.
Evaluation results of the system's implementation show that the primary obstacles lie not in the machinery, but in the organization. Outdated standard operating procedures (SOPs), a lack of operator understanding regarding new workflows, and suboptimal data integration with Enterprise Resource Planning (ERP) systems are the core issues.
Key Points
The main barriers to CCMS implementation are SOPs, operator competence, and data integration, rather than the technology itself.
Input on the production floor is not always synchronized with data in the central ERP, increasing the risk of human error .
A constrained optimization framework explains why efficiency is difficult to achieve as long as internal bottlenecks remain unresolved.
Updating SOPs, training operators, and aligning data architecture are prerequisites, not merely supplementary tasks.
Three Interconnected Problems
These three issues converge at a single point: increased human error and decreased production data accuracy.
Operators working with legacy SOPs often struggle when faced with CCMS digital interfaces that require different logic. Consequently, data entered on the production line does not always synchronize with records in the central ERP.
This situation creates an information gap between the production floor and decision-makers.
Technology investments like CCMS are fundamentally designed to reduce human error and accelerate data flow. However, sophisticated equipment does not automatically generate efficiency if work rules are not updated accordingly.
Many SOPs still rely on manual mechanisms, leading to unclear responsibilities, duplicate recording, and gaps in data quality control.
Old Rules, New Systems
The human resource (HR) competency gap further exacerbates the situation. Minimal training leads some operators to rely on old habits, while digital systems demand discipline in entering data in real-time.
When outdated rules meet an unprepared workforce, integration between CCMS and ERP can stall, hindering the efficiency gains the company should have achieved.
Managerial economics literature supports these findings. A mismatch between the competencies workers possess and those required can hinder operational efficiency (Davlyatova, 2025).
Meanwhile, companies that develop competency-based HR are considered more capable of narrowing skill gaps and improving production outcomes (Judrups et al., 2015).
The Numbers Speak
The challenge of digital transformation is not limited to a single company or factory.
A 2018 McKinsey survey of 1,793 respondents found that only about 23 percent stated that digital transformation in their organizations successfully improved performance. Meanwhile, only about 16 percent reported sustained performance improvements.
In several relatively traditional industries, such as oil and gas, automotive, infrastructure, and pharmaceuticals, the success rate of digital transformation is reported to be in the 4–11 percent range.
In the manufacturing sector, about 70 percent of factories are reported to still collect data manually, according to Manufacturing Leadership Council data cited from secondary sources. This condition leaves digital systems lacking the real-time data that should be a primary source for decision-making.
The impact of using manual SOPs can also be seen in controlled experiments on mechanical assembly processes.
Paper-based instructions in the experiment required an average of 1,084.8 seconds, while using step-by-step digital instructions required only about 599.4 seconds. This means processing time decreased by approximately 44.75 percent.
The number of errors also decreased from 56 to nine.
However, the sample in that experiment was relatively small and the participants were beginners. Therefore, these figures are better used as an indication of the direction of digitalization benefits, rather than as a precise metric applicable to every factory.
Regarding data quality, Gartner estimates that poor data quality can cause an average loss of approximately USD 12.9 million per year for an organization.
Analysis: Reading the CCMS Case Through Constrained Optimization
The CCMS implementation case can be explained using the framework of constrained optimization in managerial economics.
In this approach, production efficiency is treated as an objective function that can only be maximized if various internal constraints are first aligned.
In the CCMS case, these constraints include SOPs that still use old patterns and the operator competency gap.
This logic aligns with the Lagrange multiplier method used to solve conditional optimization problems by incorporating constraints into the objective function.
The Lagrange multiplier (λ) represents the shadow price , which is the change in the optimum value when a constraint is relaxed by one unit.
Conceptually, if the economic benefit of relaxing a constraint is greater than the cost required, investment in improving SOPs, increasing operator competence, or fixing data architecture becomes economically relevant.
Hypothetical Illustration: If Investment Portions are Imbalanced
As an illustration, suppose the efficiency index is formulated as:
Q = x × y
In this illustration, x is the CCMS technology investment, while y is the complementary investment covering SOPs, training, and data architecture. The total budget is assumed to be IDR 100 billion.
If the investment composition is split 50:50, the value of Q reaches 2,500, or 100 percent of the optimum point in the model.
Meanwhile:
A 70:30 composition yields Q = 2,100, or 84 percent.
An 80:20 composition yields Q = 1,600, or 64 percent.
A 90:10 composition yields Q = 900, or 36 percent.
These figures are purely illustrative based on a hypothetical function, not actual case data, and not a budget proportion recommendation.
The message from this illustration is simple. The more imbalanced the investment allocation between technology and its supporting factors, the greater the likelihood that actual results will deviate from the optimal potential.
Prerequisites, Not Supplements
The evaluation of CCMS implementation shows at least three improvement steps that can be viewed as primary prerequisites in the manufacturing digitalization process.
1. SOP Updates
Digital SOPs with a centralized repository, version control, and clear review cycles can help maintain process standardization while reducing variation in work execution.
2. Continuous Operator Training
Human competence is a critical factor in determining whether digital systems can be operated correctly and produce consistent data.
Training is not sufficient if done only when the system is first introduced; it must be conducted continuously to keep pace with technological developments and changes in work processes.
3. Data Architecture Alignment
Integration between machines, CCMS, and ERP is necessary to create a single, reliable source of data for decision-making processes.
Without such integration, data from the production floor risks differing from the information received by management.
Successful digital transformation is also often linked to budget allocation for training and change management. Some secondary sources mention a range of 20–30 percent of the budget, although this figure cannot be applied uniformly to all companies.
Implementation success can be monitored using several indicators, such as assembly time per unit, number of errors, percentage of work still requiring assistance, and time required for operator orientation.
Meanwhile, figures originating from system vendors, including claims of a 40–50 percent reduction in training time, should be treated with caution as they are promotional and must be verified based on each company's specific conditions.
A Warning for the Industry
These findings can serve as evaluation material for manufacturing companies that are currently or planning to digitalize their production lines.
Investment evaluation should not focus solely on technological capabilities. Projections of Net Present Value (NPV) and Internal Rate of Return (IRR) also need to consider conservative scenarios, including the possibility that technology benefits are not fully realized due to adoption failures at the organizational level.
Without comprehensive improvements, internal constraints that hinder production optimization have the potential to recur. Consequently, even sophisticated digital systems cannot operate at their maximum capacity.
Ultimately, technology only opens the opportunity for efficiency. Actual efficiency remains dependent on how well a company aligns work rules, human competence, and data quality with the technology being used.
