Preventive action

Preventive action is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Preventive action rather than just read about it. In short: A preventive action is a change implemented to address a weakness in a management system that is not yet responsible for causing nonconforming product or service. Candidates for preventive action generally result from suggestions from customers or participants in the process but preventive action is a proactive process to identify opportunities for improvement rather than a simple reaction to identified problems or…

Key takeaways

  • Preventive action belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Preventive action to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Preventive action from memory before moving on to harder problems.

Reference excerpt

A preventive action is a change implemented to address a weakness in a management system that is not yet responsible for causing nonconforming product or service. Candidates for preventive action generally result from suggestions from customers or participants in the process but preventive action is a proactive process to identify opportunities for improvement rather than a simple reaction to identified problems or complaints. Apart from the review of the operational procedures, the preventive action might involve analysis of data, including trend and risk analyses and proficiency-testing results. The focus for preventive actions is to avoid creating nonconformances, but also commonly includes improvements in efficiency. Preventive actions can address technical requirements related to the product or service supplied or to the internal management system. Many organizations require that when opportunities to improve are identified or if preventive action is required, action plans are developed, implemented and monitored to reduce the likelihood of nonconformities and to take advantage of the opportunities for improvement. Additionally, a thorough preventive action process will include the application of controls to ensure that the preventive actions are effective. In some settings, corrective action is used as an encompassing term that includes remedial actions, corrective actions and preventive actions.

Risk and decision making Preventive actions rely upon on the consequences of change. Once changed, inevitably, risks should be taken into consideration. In this case preventive actions aim to minimize or, where possible, eliminate the risks. Risks arise when little is known and understood about a particular situation. The chances of risk are minimized whilst one has better knowledge of the opportunities and consequences that could follow a situation. In order to reduce risk, a full analysis of potential best and worst results is required. Before taking into consideration any plan, people should be aware of the consequences of both success and failure. Not only the internal aspects - capability, expertise and willingness of staff- but also the external aspects of an organisation - stakeholders, customers, clients - should be assessed. Strategic risk management works with defining an organisation's approach to risk in terms of condition, attitudes and expertise. It identifies the possible areas of risk and assures that the proper approach is used. Then operational risk management will insure that steps for minimizing or eliminating the risk are followed. A strategic approach of the risk management includes studying the environment and being aware of the issues that must be considered in any situation. Risks can occur due to a range of unexpected possible and potential events outside of the organisation's control, such as: political instability, change in currency, changes of the weather which could lead to a change in customer behavior, etc. Therefore, in an organisation it is important to know and understand what events could take place, where and why. So, managers should prioritize some steps of preventive actions in order to anticipate these kind of issues, especially focusing more on:

Patterns of behavior Accidents Single events and errors "Patterns of behavior" relates to the morale and motivation of people. The effects of human behavior (such as victimization, bullying, harassment and discrimination) could affect confidence, weakening the relationships meant to lead to performance. Accidents could happen anytime and anywhere. Thus, an organisation has to assure that the accidents are kept to a minimal level. In this situation preventive actions should focus more on the nature and quality of the working environment, safety aspects and technology. Single events and errors are very hard to be managed and impossible to be eliminated. The risk should be kept at a minimum through supervision systems, regular inspections and procedures. In order to perform a change, an organisation has to do a forecast, deeply understanding where that event could lead and its consequences. Thus, the risk of a particular event and its probability of occurring should be clear. Using this information, one can understand and better make future decisions, proposal and initiatives.

Examples in management Preventive actions differ from one organisation to another. Their number is vast, among them counting:

Assessing business trends Monitoring processes Notifications regarding any situation Perform risk analysis Assessing new technology Regular training and checking Recovery planning Safety and security policies Audit analysis

Technology safety and security Nowadays, due to fast changes in engineering, there is a large emphasis in the enhancement of safety and security regarding technology. However, in order to avoid some issues, more powerful safety analysis techniques are constantly being developed. As safety and security issues can occur anytime, intentionally or not, more preventive strategies against loss or hacking are enhanced. These actions aim to focus on the possible causes of the problem, rather than solving an already critical situation.

Worked examples

Example 1 — a first encounter with Preventive action

Start with the simplest possible case. Write down what Preventive action claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Preventive action before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Preventive action ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Preventive action

In research
Preventive action appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Preventive action in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Preventive action is common in secondary-school and first-year university syllabi. It links to neighbouring topics Prevention, Quality management, Reliability engineering, so understanding it makes those chapters shorter.
In everyday life
Look for Preventive action outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
