APPLYING STATISTICAL PROCESS CONTROL (SPC) AS A TOOL FOR QUALITY CONTROL

Law Learning Outcomes


The program provides methods for quality control by applying statistical tool for use in production processes, but also means of control (process, product).

This approach allows the appraiser to rule on the relevance of the observed data whether to continue, to recalibrate or to stop the process.

The control can be applied in monitoring a single to various characteristics (qualitative and/or quantitative) of production, follow up physical or chemical parameters of process such as assays of active ingredients previously stabilised or neutralised.

The  main  aim  for  attendees  is  to  grasp versatile and relevant control tools

available, and operate them in single or combined way.

Times and costs are mandatory gages to streamline the implied tools in front of a wide range of situation and the required level of control vs risk management.

    

CUSUM Control Chart Prerequisites

Knowledge of quality tools such as (5M, Ishikawa, brainstorming), P values and statistical significance in processing computed data.

Workshop Organisation

  

Normal Distribution Organisation of Sessions


This Training program is currently provided inhouse or in our training centre, upon request.

The duration of the training is 3 days. Training is organised in six sessions (3,30 h each). Session schedule can be tailored according to organisational needs.


Law Teaching Method

This course is highly interactive and the participants will undertake several practical case studies related to a covered topics. The training includes extensive support provided to participants by the facilitator on the overall schedule.


Delivery of course materials and exercises (and corrected media guide) to each participant.
