Assessment Guidance

This unit must be assessed in a work environment and must be assessed in accordance with the ‘Common Requirements for National Vocational Qualifications (NVQ) in the QCF’ which can be downloaded from Semta’s website: http://www.semta.org.uk/training_providers__awarding/national_occupational_standard/qca_assessment_requirements.aspx

Additional assessment requirements have been published by Semta. These additional assessment requirements are set down in Semta’s Business-Improvement Techniques Level 4 unit assessment strategy which can be downloaded from Semta’s website: http://www.semta.org.uk/training_providers__awarding/national_occupational_standard/qca_assessment_requirements.aspx

Unit specific additional assessment requirements:

The word lead is used throughout this unit. This means that although the outcomes of this unit may be carried out and achieved as part of a team, it is necessary for the learner to demonstrate a level of overriding management and direction of the activities as a whole. This may be in the form of coordinating multiple activities, using company strategies and objectives to determine activity focus and managing projects involving improvement initiatives. The learner will have a leading role in controlling activity focus and planning.

Specific quantifiable and auditable personal contributions in the achievement of this unit are also required to fulfil this unit.

Competence in all the areas covered by the standard is required.

The learner’s ability to combine the performance statements specified when applying the principles and processes of this unit must be demonstrated.

1.2

Lead the activities within their area of responsibility to include all of the following:

• set out an communicate the purpose of the improvement activities

• involve the team in planning how the improvement activity will be achieved

• ensure each team member has individual objectives and understands how these objectives contribute to the overall improvement objective

• provide advice and support the team to achieve both team and individual improvement objectives

• motivate the team to present their own improvement ideas

• encourage the team and/or individuals to take the lead where appropriate

• agree the implementation of the improvement ideas

• negotiate any physical and/or financial resources required to implement the improvement activity (where appropriate)

• monitor the progress of improvement activities

• deal with any organisational problems identified during the improvement activity

1.3

Work to, and ensure compliance with all the required process monitoring documentation and work instruction sheets

1.4

Approve the process on which the process analysis is to be carried out

1.5

Consult with relevant people and lead the gathering of the necessary data for analysis

1.6

Lead the application of the principles and processes of statistical process control to the chosen process

2

1b. Lead statistical process control (SPC) activities (continued)

2.1

Lead the performing of basic statistical process control, using appropriate tools and techniques

2.2

Lead the use of statistical and graphical methods to represent the process conditions

2.3

3

2a. Know how to lead statistical process control (SPC) activities

3.1

Describe the health and safety requirements of the area in which they are leading the process control activities

3.2

Explain how to plan the resources and time needed to carry out the agreed activity

3.3

Explain where process control fits within a continuous improvement environment

3.4

Explain how process performance affects customer satisfaction and process costs

3.5

Explain where and why statistical process control is used, the benefits, and how it is applied

3.6

Describe the importance of standardisation within a process operation, and why process performance can only be determined when it is controlled

3.7

Explain how process control can improve process performance

3.8

Describe the benefits of prevention and detection

Describe the two types of variation within a process (common cause, special cause), and the impact they have within the process

4

2b. Know how to lead statistical process control (SPC) activities (continued)

4.1

4.7

Explain how to explain the terms and calculate mean, median, mode, standard deviation, range and variance

4.8

Explain how to explain and calculate process capability (Cp and Cpk)

4.9

Describe the extent of their own authority, and to whom they should report in the event of problems that they cannot resolve
