Applying quality function deployment (QFD)
Overview
This standard covers the competencies required for applying quality function deployment (QFD). It involves identifying the customer requirement of a product or process and obtaining all the required information necessary to perform the QFD project study. These, typically, would cover the needs and expectations of the customer and the functions and features required by the customer. You will be required to produce a matrix for the quality function deployment activity, which identifies the four phases (such as pre- planning, design deployment, process and production planning and managing deployment). You will need to analyse the information gathered (such as score matrices for relationships, technical requirements, correlations, planning and specifications) and draw conclusions as to the appropriate course of action. You will be expected to record the results of the analysis in the appropriate format to enable a report to be compiled, outlining the findings of the activity and the recommended solutions.
Your responsibilities will require you to comply with organisational policy and procedures for the activities undertaken and to report any problems with the activities that you cannot solve, or are outside your responsibility, to the relevant authority. You will need to ensure that all the necessary documentation is completed accurately and legibly. You will be expected to take full responsibility for your own actions within the activity and for the quality and accuracy of the work that you produce.
Your underpinning knowledge will provide a good understanding of quality function deployment and provide an informed approach to the techniques and procedures used. You will need to understand the principles and application of QFD, in adequate depth to provide a sound basis for carrying out the activities to the required criteria.
Applying safe working practices will be a key issue throughout.
Performance criteria
You must be able to:
- work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
- identify the customer requirement of a product or process using quality function deployment
- obtain all the required information necessary to perform the quality function deployment study
- carry out the quality function deployment project
- analyse the information gathered and draw conclusions as to the appropriate course of action
- record the results of the analysis in the appropriate format
- produce a report outlining the findings and the recommended solutions
Knowledge and Understanding
You need to know and understand:
- how to work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
- the advantages of using quality function deployment
- the 'quality lever' and how quality function deployment fits this model
- the terms 'house of quality' and 'voice of the customer'
- how quality function deployment relates to potential failure modes and effects analysis, design of experiments, value analysis, control plans, Pugh concept diagrams
- how to carry out a quality function deployment activity, and the tools and techniques used
- the four phases of quality function deployment (pre-planning, design deployment, process and production planning, managing deployment)
- how to identify the necessary inputs and outputs for each of the phases
- what are the customer's requirements within the project, in terms of needs and expectations, features and functions
- how to produce matrices for relationships, specifications, technical requirements and planning
- how to score the matrices within the quality function deployment
- the extent of your own authority within the project and whom you should report to, in the event of problems you cannot resolve
Scope/range
Scope Performance
Produce a matrix for a quality function deployment project which identifies the four phases as follows:
- pre-planning
- design deployment
- process and production planning
- managing deployment
Determine the customer requirements within the project in terms of:
- needs and expectations
- functions
- features
Identify within the quality function deployment project all the:
- necessary inputs and how to acquire them
- the outputs from each of the four phases and their execution
- customer rankings
- substitute quality characteristics
Produce and score matrices for three of the following:
- relationships
- technical requirements
- correlations
planning
specifications
