Scientific Method
A proposed explanation that can be tested by experiment.
What is hypothesis
The first step in the engineering design process, where needs, requirements, and constraints are identified.
What is defining the problem?
The prioritized list of tasks and user stories the team works from.
What is the product backlog?
This final step ensures findings are shared with others through reports, papers, or presentations.
What is communicating results
Building a working model of a solution is called this.
What is prototyping?
A short description of a feature from the user’s perspective.
What is a user story?
Unlike engineering design, the scientific method primarily aims to create this.
What is new knowledge or understanding
This stage involves going back and improving your design after testing.
What is iteration (or redesign and improve)?
This short daily meeting keeps the Agile team aligned.
What is the daily stand-up (or daily scrum)?
The part of an experiment that does not receive the tested variable and is used for comparison.
What is the control group?
The limits placed on a design, such as cost, safety, or material availability, are called this.
What are constraints?
At the end of a sprint, the team meets to reflect on what went well and what could improve.
What is the sprint retrospective?
When repeated experiments by different scientists yield the same results, the process is said to have this quality.
What is reproducibility (or reliability)
The process of weighing multiple possible designs against requirements before selecting one.
What is trade-off analysis (or evaluating alternatives)?
The document or checklist that ensures a backlog item is complete before it is considered finished.
What is the Definition of Done (DoD)?
