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.

Overview of assessment

Evidence should be available of the person's facilitation of the operation of the JIT system and their making of recommendations for/making improvements.

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:

identify the JIT system and practices used in their team or area of responsibility

identify and monitor JIT key measures

solve JIT-related problems to root cause

implement and monitor JIT-related changes to operations and practices.

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:

workplace procedures and plans relevant to work area

specifications and documentation relating to planned, currently being implemented, or implemented changes to work processes and procedures relevant to the assessee

documentation and information in relation to production, waste, overheads and hazard control/management

reports from supervisors/managers

case studies and scenarios to assess responses to contingencies.

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:

demonstration in the workplace

workplace projects

suitable simulation

case studies/scenarios (particularly for assessment of contingencies, improvement scenarios, and so on)

targeted questioning

reports from supervisors, peers and colleagues (third-party reports)

portfolio of 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.

Required skills

Required skills include:

identifying KPIs for JIT system in team or area of responsibility

analysing the JIT/kanban implementation in the team or area and the relevant sections of the internal and external value stream, including identifying people-related needs and issues

identifying and implementing quick fix to JIT problems

using formal problem solving procedures (e.g. root cause analysis (RCA))

developing formal and informal communication procedures with others in work area, team leaders, other employees and value stream members relevant to JIT implementation

establishing sources of assistance in the organisation for people experiencing difficulty with competitive systems and practices changes

interpreting procedures and instructions relevant to own expertise for others

establishing KPIs for own work

Required knowledge

Required knowledge includes:

JIT principles relevant to operations and processes in own area or team and in the organisation generally

procedures for making/recommending improvements

typical reasons for delays/storages/inventories in the team or area of responsibility and methods of reducing/eliminating them

skill gap analysis and methods of filling skill gaps

principles of the operations process relevant to the section/team

production data generated by the process and its application to JIT

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:

lean operations

agile operations

preventative and predictive maintenance approaches

monitoring and data gathering systems, such as Systems Control and Data Acquisition (SCADA) software, Enterprise Resource Planning (ERP) systems, Materials Resource Planning (MRP) and proprietary systems

statistical process control systems, including six sigma and three sigma

JIT, kanban and other pull-related operations control systems

supply, value, and demand chain monitoring and analysis

5S

continuous improvement (kaizen)

breakthrough improvement (kaizen blitz)

cause/effect diagrams

overall equipment effectiveness (OEE)

takt time

process mapping

problem solving

run charts

standard procedures

current reality tree

Competitive systems and practices should be interpreted so as to take into account:

the stage of implementation of competitive systems and practices

the size of the enterprise

the work organisation, culture, regulatory environment and the industry sector

JIT

JIT refers to:

a production scheduling concept that calls for any item needed at a production operation (whether raw material, finished item, or anything in between) to be produced and available precisely when needed, neither a moment earlier nor a moment later

Kanban

Kanban is a card or sheet used to authorise production or movement of an item; when fully implemented, kanban operates according to the following rules:

all production and movement of parts and material take place only as required by a downstream operation (i.e. all operations and procurement are ultimately driven by the requirements of final assembly or the equivalent)

the specific tool which authorises production or movement is called a kanban. The word literally means card or sign, but it can legitimately refer to a container or other authorising device. Kanban have various formats and content as appropriate for their usage (e.g. a kanban for a vendor is different than a kanban for an internal machining operation)

Kanban is typically applied to batch type operation and the production is measured in units produced. In continuous processing organisations, production is measured in terms of production rate (e.g. kg/h, tonne/day) and rate is increased/decreased according to the flow authorisation which may be a kanban (e.g. ticket, order from a supplier) or may be a SCADA signal from a remote facility (e.g. customer tank) saying that resupply is required or similar

SCADA

SCADA refers to:

a number of systems which automatically collect critical process data, perform required mathematical manipulations on it and then make control decisions and/or give required information to personnel for action

Key measures

Key measures may include:

inventory levels

lead time

In Full, On Time and In Specification (IFOTIS) delivery

productivity/production rate

other measures of pull through the value stream

quality

Quick fix

Quick fix refers to:

action taken to immediately and cheaply control a problem, prevent it getting worse and/or ameliorate its impact, but which does not necessarily solve it long term

Pull system

Pull refers to:

a system of making to demand rather than for stock or to a forecast

Value stream

The value stream begins with the customer and includes all actions (both value-adding and non-value added) by both internal sections/departments and external organisations to meet a customer requirement.

Depending on the operations and the customer requirement, stages where value stream actions may occur include:

sales outlet/representative

information gathering, data analysis and research

product design

raw material sourcing

intermediate processing

final assembler/collation/preparation

support services (e.g. accounting, finance and legal)

storage and delivery to customer

after market support
