Implement a green multi-unit manufacturing process MFG 8-1/2
Implement a green multi-unit manufacturing process focuses on the application of underpinning concepts and techniques in the multi-unit manufacturing of goods. A manufacturing process enables the multi-unit production of a technological outcome. Technological outcomes may include technological products that are components of another product, or the product as a whole. It is important to remember that the primary focus for this standard is the green manufacturing process and the quality control of the outcomes, that is, on the process and implementation. The manufacturing process will need to be run more than once in order to get the feedback and evaluation in order to improve the process. (At level 8, knowledge of manufacturing also covers human factors in design that is, there is no level 8 specific for human factors in design).
Learning objective: MFG 8-1/2
Students will:
- develop understanding of, and implement, a "green" manufacturing process.
Indicators
- Analyses a technological outcome to determine its suitability for "green" manufacture.
- Makes design changes as required for the technological outcome guided by contemporary judgment criteria.
- Establishes specifications, including tolerances, required of the outcome that is to be manufactured.
- Discusses how and why quality management procedures have been important in changing manufacturing practices to better support "green" considerations.
- Monitors quality control procedures that allow for on-going monitoring to enhance the review and refinement of the manufacturing process to better suit the nature of the outcome and enhance its success in meeting "green" considerations.
- Justifies the level of success the manufacturing process has attained in meeting "green" considerations.
Progression
Initially students will use a defined technological outcome suitable for manufacture that has established manufacturing specifications. They will determine and implement the manufacturing system by considering the type of outcome, the resources and the techniques to be used. At level 8 students progress to the incorporation of quality management and quality control procedures in the development and implementation of a "green" manufacturing process.

Teacher guidance
To support students to develop and implement an effective manufacturing process at level 8, teachers could:
- provide opportunity for discussion of how "green" considerations are having an increasing influence on technological outcomes and their manufacture
- support students to develop their understanding of "green" manufacturing processes
- discuss contemporary judgment criteria, based on the principles of good design, and how these may impact on the development and implementation of "green" manufacturing processes
- provide examples of optimisation in terms of energy and resources that exemplify "green" manufacturing processes
- support students to analyse a technological outcome to determine its suitability for "green" manufacture and to make design changes as required
- support students to modify the techniques and use of resources and the quality control procedures established to tailor the "green" manufacturing process to the constraints and/or opportunities of the manufacturing location
- support students to evaluate the success of their manufacturing process in meeting "green" considerations.

Contexts for teaching and learning
A green manufacturing process prioritises green considerations in keeping with judgment criteria used to determine good design. Green considerations include optimising the use of energy and resources and will also address design quality as guided by good design judgment criteria.
- To understand the concepts of green manufacturing, students could explore New Zealand companies that have sustainable practices such as Miranda Brown Conscious Cloth, Starfish, The Green Monkey Baby Food Company.
Manufacturing can be incorporated into a teaching and learning programme where students design and create technological outcomes to meet a developed brief and use knowledge of modeling and materials/systems within this context. This links to brief development, planning for practice, outcome development and evaluation, technological modeling and technological products and systems, where students implement a one-off solution and then can move into considering manufacturing (
refer to key messages from the standard). Support students to:
- understand the limitations and constraints on their practice within the classroom environment such as the sourcing sustainable materials and finishes
- consider such things as the materials and equipment available, calculating the materials and the scale of their manufacturing run and the resources required for this, developing flow charts, specifications and quality control checks to ensure the consistency and quality of their outcomes, codes of practice and the means to adapt the processes in response to their quality control processes and evaluation.
Literacy considerations
Support students to develop skills such as:
- using correct conventions in flow charting a manufacturing process
- using the specialised vocabulary of manufacturing, flow charting and quality control (demonstrating understanding of such things as HACCP or Six Sigma systems).

Assessment for qualifications
The following achievement standard could assess learning outcomes from this learning objective:
- AS91618 Generic technology 3.13: Undertake development and implementation of a "green" manufacturing process
Key messages from the standard
- This standard requires students to develop and implement a green manufacturing process with quality control procedures that guarantee its effectiveness – ensuring that the majority of units in a multi-unit production run meet the established specifications and tolerances.
- When selecting a manufacturing context, ensure that it is feasible in terms of timeframe, complexity and resources, and that it gives students scope to demonstrate that they meet all the requirements of the standard.
- Several students may participate in the actual manufacture as long as they can individually demonstrate the evidence for the standard.
- There are two approaches described in the assessment resources:
- 1. The student could investigate an outcome, determine its suitability for green manufacture, establish the manufacturing specifications for the textile item and implement the green manufacturing process. Or
- 2. The students may have been engaged in technological practice, have fully established the specifications for an item that is suitable for green manufacture, and are ready to develop and implement a green manufacturing process to produce a larger run.
- Students should explore the use of good design judgment criteria that includes such things as: sustainability, accessibility, functionality, quality of manufacture, emotional resonance, endurance, social benefit, aesthetic quality, ergonomic fit, affordability. This aligns with the learning that would support students understand the Judgment of design which is assessed using achievement standard 3.10. Students should be guided by these criteria when considering and evaluating the design of their outcome and be able to adapt the processes for manufacturing. They will need to consider such things as the materials and equipment available, calculating the materials and the scale of their manufacturing run and the resources required for this, developing flow charts, specifications and quality control checks to ensure the consistency and quality of their outcomes, codes of practice and the means to adapt the processes in response to their quality control processes and evaluation.
