Design for the life cycle includes consideration of social and environmental impacts.
Design for the life cycle
taking into account economic costs, and social and environmental impacts of the product, from the extraction of raw materials to eventual reuse or recycling of component materials environmental impacts
including manufacturing, packaging, disposal, and recycling considerations Personal design interests require the evaluation and refinement of skills.
Tools and technologies can be adapted for specific purposes.

Curricular Competencies
Students are expected to be able to do the following:
Applied Design
Understanding context
- Engage in a period of user-centred researchand empathetic observationuser-centred researchresearch done directly with potential users to understand how they do things and why, their physical and emotional needs, how they think about the world, and what is meaningful to themto understand design opportunitiesempathetic observationaimed at understanding the values and beliefs of other cultures and the diverse motivations and needs of different people may be informed by experiences of people involved; traditional cultural knowledge and approaches; First Peoples worldviews, perspectives, knowledge, and practices; places, including the land and its natural resources and analogous settings; experts and thought leaders
Defining
- Establish a point of view for a chosen design opportunity
- Identify potential users, intended impacts, and possible unintended negative consequences
- Make inferences about premises and constraintsthat define the design space, and develop criteria for successconstraintslimiting factors, such as task or user requirements, materials, expense, environmental impact
- Determine whether activity is collaborative or self-directed
Ideating
- Identify and examine gaps for potential design improvements and innovations
- Critically analyze how competing social, ethical, and sustainability considerations impact creation and development of solutions
- Generate ideas to create a range of possibilities and add to others’ ideas in ways that create additional possibilities
- Evaluate suitability of possibilities according to success criteria, constraints, and potential gaps
- Work with users throughout the design process
Prototyping
- Choose an appropriate form, scale, and level of detail for prototyping, and plan procedures
- Analyze the design for the life cycle and evaluate its impactsimpactsincluding social and environmental impacts of extraction and transportation of raw materials; manufacturing, packaging, and transportation to markets; servicing or providing replacement parts; expected usable lifetime; and reuse or recycling of component materials
- Visualize and construct prototypes, making changes to tools, materials, and procedures as needed
- Record iterationsof prototypingiterationsrepetitions of a process with the aim of approaching a desired result
Testing
- Identify and communicate with sources of feedbacksources of feedbackmay include peers; users; First Nations, Métis, or Inuit community experts; other experts and professionals both online and offline
- Develop an appropriate testof the prototype, conduct the test, and collect and compile dataappropriate testincludes evaluating the degree of authenticity required for the setting of the test, deciding on an appropriate type and number of trials, and collecting and compiling data
- Evaluate design according to critiques, testing results, and success criteria to make changes
Making
- Identify appropriate tools, technologies, materials, processes, cost implications, and time needed
- Create design, incorporating feedback from self, others, and results from testing of the prototype
- Use materials in ways that minimize waste
Sharing
- Decide how and with whom to sharecreativity, or share and promote design and processessharemay include showing to others or use by others, giving away, or marketing and selling
- Share the product with users and critically evaluate its success
- Critically reflect on plans, products and processes, and identify new design goals
- Evaluate new possibilities for plans, products and processes, including how they or others might build on them
Applied Skills
Apply safety procedures for themselves, co-workers, and users in both physical and digital environments
Individually or collaboratively identify and assess skills needed for design interests
Demonstrate competency and proficiency in skills at various levels involving manual dexterity and machining and welding
Develop specific plans to learn or refine identified skills over time
Applied Technologies
Explore existing, new, and emerging tools, technologies, and systems to evaluate suitability for design interests
Evaluate impacts, including unintended negative consequences, of choices made about technology use
Analyze the role that changing technologies play in machining and welding contexts

future career options and opportunities in machining and welding
interpersonal skills for interacting with colleagues and clients
interpersonal skills
for example, professional communications, collaboration, ways of explaining visuals Note: Some of the learning standards in the PHE curriculum address topics that some students and their parents or guardians may feel more comfortable addressing at home.
