We only cover the most basic chart types here, so it would be necessary to have help from a process expert or statistician if your needs are more sophisticated. As well, you may need or benefit from Process Behavior Chart software if not performing your own calculations. 

The SkiBlades defect rate was mostly steady, with one exception on day 13. A team of process experts then discovered a correlation between fluctuations in the temperature of the resin curing oven and the defective pulls that broke away from the boots. At the team s recommendation, the temperature controller was replaced with a more modem unit, and the oven temperature was recorded and monitored using a Process Behavior Chart. 

A Cause Effect Matrix enables the numerical representation of process inputs and outputs, and the relationships between them. This quantifies the knowledge of each process expert.

When designing a chemical plant, expertise from multiple domains is required. For example, in the case of our Polyamide-6 reference process experts from chemical engineering and plastics engineering have to cooperate. Plastics engineering is needed to take care of the last step of the chemical process, namely compounding, which is performed with the help of an extruder. 

Semi-formal representations can be used as an intermediate step for the generation of a model with the intended level of detail and formalization First, the operations are specified by chemists or process experts on a conceptual, semi-formal level, and subsequently formalized and refined. Since such semi-formal representations are currently missing, inadequate workarounds like spreadsheets or informal documents are often used in industrial practice. 

They combine both the results of explicit analysis done by process experts, and the multi-step analysis of the process data done within in the project.

Chemists who are used to the development path of procedural programs for instrumental control or data analysis, will find the development path of an expert system to be a far more convoluted process. Expert systems should be viewed as evolving rather than being constructed as a one time program. The specification and prototyping stages encompass a much larger portion of the system development time. Furthermore, the... 

Validation maintenance, an ongoing activity for manufacturing processes [11], continues through the life cycle of the process with a changing focus as the process matures [20]. There is a need to address the process life cycle as a whole and not to suspend process validation after three production scale runs are completed [14]. To support this life-cycle approach, process expert teams are created to rapidly resolve process deviations, determine trends toward loss of control, comply with regulatory requirements, assess process change impact, and identify areas for process improvement [11].

The process expert supplies knowledge about the process itself. He or she will often be a chemical engineer. Generally, he is expected to explain how the process works, what the basic chemistry is, and what would be the process impact of identified hazards. Sometimes, the process expert is also the team leader. If this is the case, he or she must make it clear which role they are filling as the discussion progresses. 

The LCI analysis is the heart of the LCA process since it involves with actual data collection, validation, and calculation procedures. Data collection sheets should be prepared and data need validation process by process experts as reviewers. After validation, data can be converted to units per functional unit basis. The functional unit is the reference unit of a product or process for which quantified performance is measured in an LCA study. Where allocation or partitioning of impacts are required due to multiple products or reuse and recycling in the process, the impacts can be shared based on mass allocation of the flow by weight basis or economic allocation based on annual average prices over a few years. According to international standards, allocation should be avoided where possible by expanding the process system. If it cannot be avoided, the basis of allocation and procedures should clearly be stated. 

There are many examples of subject matter experts (SMEs) at most facilities, such as process expert, emergeney relief sizing, risk assessment, mechanical integrity, incident investigation, and PHA leadership. In some cases these tasks are clearly spelled out as part of the job description for these positions, but in other cases people may have developed into de facto SMEs over time. These skills might not be captured as critical competencies for their positions. 

A process expert or two who works daily in the area to be improved. People who have a passion for continuous improvement. 

A facilitator has to invest time and energy to win over the process expert on any kaizen team. They are one of the keys to the team s success. 

Now that everyone understands the role they will play, it is time to take the team to the work area where the kaizen team will observe the targeted work process. Notice that this step is called team orientation on the process map. This is the facilitator s opportunity to ask the process expert to both brief the team on any safety hazards they should be aware of, and to introduce the team to their co-workers in the area. The co-workers should be gathered together and briefed on what the team s object for the event will be. Keeping all the workers in the area informed of the team s actions will help to guarantee their acceptance of the changes to come. 

The FMEA approach has been around for a very long time. Before any documented format was developed, inventors and process experts would try to anticipate what could go wrong with a design or process before it was developed or tried. The FMEA discipline was first formalised in the late 1940s by the US Military (refer MIL-P-1629A, page 2) where it used as a reliability evaluation technique to determine the effect of system and equipment failures. Failures were classified according to then-impact on mission success and personnel/equipment safety. 

The coke drums HAZOP was performed in five full days of work with a multidisciplinary team consisted by experienced DCU operators from three different Petrobras refineries, automation specialists and process engineers responsible for the basic design of the DCU. These automation and process experts were also responsible for the coke drums Permissive Logics Matrix development. During this period, 8 nodes were assessed. 

Transparancy of the methodln the method, incident descriptions are related to base causes and to the standard scenarios. In this process, expert judgment is used. In order to make the method transparent, objective criteria are needed for this process. 

To avoid nuisance alarms etc. it is customary to use some dead-hand and On/Off delays. Process experts judgments are used to fix these values however some guideline for four commonly encountered parameters could be as in Table IX/...

It will become obvious that what is considered good design practice insofar as metals are concerned will not necessarily be good practice for processing plastics. It is advisable when in doubt to review this book, the referenced literature on the subject, or consult processing experts who know the limitations of plastics. By working in close cooperation with the plastics fabricator it is usually possible to arrive at a satisfactory compromise. 

Process experts of other disciplines should be available to be called upon as required ...
