Unit Descriptor
This unit of competency covers the skills and knowledge required to apply the theory of constraints to a process which has a constraint.
Application of the Unit
This unit applies to individuals who, as part of their work, are able to apply the theory of constraints to improve the operability of a constrained process (a process with at least one constraint) where it occurs in their team or work area or as part of their responsibilities. This unit identifies and works within the imposed constraint. This process may be colloquially known as ‘drum-buffer-rope’ approach. This unit does not seek to remove or reduce the constraint (see MSS405024A Apply the theory of constraints ). The unit will normally be applied as part of an organisation’s improvement strategy and in conjunction with other competitive systems and practices units.
The person will typically be a technician, team leader or other person who works with others in the bringing of change to an organisation as part of a formal team or otherwise. The unit includes liaison and communication with others, as required.

Elements and Performance Criteria Pre-Content
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |

Required Skills and Knowledge
This section describes the skills and knowledge required for this unit. |
Required skills |
Required skills include:
|
Required knowledge |
Required knowledge includes:
|
Evidence Guide
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. |
|
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
A person who demonstrates competency in this unit must be able to provide evidence of the ability to:
|
Context of and specific resources for assessment |
Assessment of performance must be undertaken in a workplace using or implementing one or more competitive systems and practices. Access may be required to:
|
Method of assessment |
A holistic approach should be taken to the assessment. Competence in this unit may be assessed by using a combination of the following to generate evidence:
In all cases it is expected that practical assessment will be combined with targeted questioning to assess underpinning knowledge. Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability. |
Guidance information for assessment |
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the candidate and the work being performed. |
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
|
Competitive systems and practices |
Competitive systems and practices may include, but are not limited to:
Competitive systems and practices should be interpreted so as to take into account:
|
Constraint/capacity constrained resource |
A capacity constrained resource refers to:
|
Drum |
The capacity constrained resource is often referred to as the drum, as its output provides the ‘drumbeat’ for the output of the entire system or process |
Buffer |
Buffer refers to:
|
Optimum use of capacity |
Optimum use of capacity refers to:
|
Supply schedule (‘rope’) |
Supply schedule refers to:
|
Delivery schedule |
Delivery schedule refers to:
|
Appropriate action |
Appropriate action may include:
|
