Lectures 1-4 (Design 1,2 And Project Managment) Flashcards
What is used in the engineering design cycle? (as opposed to the science analyses cycle)
Existing knowledge
What is the purpose analysis section of the engineering design cycle?
To have a Goal and define the function
What is the synthesis section of the engineering design cycle?
structure
what is the outcome of the engineering design cycle
A New world
What are the three i’s of design?
Identify, Invent, Implement
During the identify phase of the design cycle how do you empathize with th users?
by involving the users and the experts
During the identify phase of the design cycle how do you identify the need of the user?
Write a need statement, consider the functions, objectives, and constraints
During the invent phase of the design cycle how do you ideate and design prototypes?
Consider all possible concepts and outcomes
During the invent phase of the design cycle how do you test?
Start cheap and fast and consider riskiest ideas first
what can be done during the implement phase of the design cycle ?
Strategy development. Ask for feedback
What’s the template for a need statement?
A way to address (problem) in/for (population)
What is a solution dependent need statements
A need statement with an implied solution
What is scoping?
researching if the need statement should be more broad or more narrow with respect to the problem and the population
what’s one con of the observing method for research?
- the observer effect
- ## is it durable in relation to the size of the project
What’s one con of the interviewing method for research?
- questions can induce bias
- may not be an accurate representation of full population
what does FOC stand for?
Function, Objectives, Constraints
Function
What the design MUST DO to meet the need
Objectives
What the design SHOULD DO ideally (max and min)
Constraints
Externally applied musts (laws, etc.)
What is the goal of a Work breakdown structure (WBS)?
Break down tasks until there is one clear deliverable, owner and time estimation.
What is FS tasks?
A task depends on another task being done before it
starts
what is SS tasks?
A task depends on another task being started before it
can start.
what is an FF task?
A task can’t end until another task also ends
what is a SF task?
A task depends on another task being started before
it finishes
What makes up a network flow diagram?
Nodes and arrows to represent tasks and time
Strong milestones
will move along with delayed tasks
Rubber milestones
will stay fixed even if tasks are delayed
What is the critical path?
The longest path from start to finish (the combination of tasks that will take the longest)
The critical path shows the shortest amount of time the whole project will take to complete.
Why is it important to monitor the tasks that make up the critical path closely?
Any delay in the critical path will delay the whole project.
What is two things that can be done to shorten the critical path?
1.Assign more resources to the critical tasks
2.Subdivide the tasks to Crete more congruent tasks
What are the three ways to gather information?
- Research
- Interviews
- Observations
What is a stakeholder?
Any party who may have an interest in a product/project or will be affected by its outcomes.
They have the capacity to support, be neutral or resist a product/project
Why is it important to identify stakeholders?
The more impact, influence and interest a stakeholder has in a product/poject the more you should try to include them in the design and process of the product.
Why is it important to analyze existing solutions?
- To determine if you should implement an existing solution
- To determine where the current gap is in existing solutions
- To determine if there is room for improvement
what’s the ideal corner?
The place in your products solution landscape that maximizes the criteria you are considering (eq. Maximize efficiency and minimum cost)
what are the perameters of brainstorming?
Need: A group of ppl, a set quantity and a set goal, quantity over quality, dont say “no”
What are the perameters of mind mapping?
expand on exsisting solutions, can be done in a group or as one person
What does SCAMPER stand for?
Substitute: exchanged or switched out
Combine
Adapt: to be more simalr to exsisting solutions
Modify: how is it made? how can that change?
Put to another use: reuse waste?
Eliminate: reduce mass?
Reverse
What is Heuristic ideation Technique?
Decompose two exsisting solutions and combine aspects of them
Works-like model
May not look or feel like final product, but functions the same way
Feels-like Model
Made of similar material, but does not function like the final product
Looks-Like Model
Shape, color, size, and/or packaging like final product but does not need to work
Is-Like Model
Combination of works-like and feels-like, but still needs iterating specifically with respect to
looks
Looks-like/is-Like Model
Model looks like and works like final device
May still need iterating
If your riskiest assumption is whether someone would be willing to wear
your product?
Looks-Like model
If your riskiest assumption is whether the material would survive in
water?
Feels-like model
If your riskiest assumption is whether the product can perform function?
Works-like model
Low fidelity model
quick, easy, inexpensive
High Fidelity model
complex, costly, time consuming
