Knowledge Problems ​
Solving: ​
Do activity: (tasks) ​
get an overview of activities you need to solve the problem.
Support Tools:
- Gantt charts: dependencies & parallel in time.
- Kanban/Scrum: For agile projects. evaluate each iteration.
Discover activity: (knowledge) ​
find knowledge you require to solve the problem. search for relevant knowledge problems. results in a list of research questions.
Decide Activity: (scope) ​
select the key areas you will focus on. state the limits of your research. Make use of a theoretical framework.
Types of problem analysis activities: ​
- Detailed problem analysis.
- Search for causes.
- Search for known solutions.
Causes: ​
- evidence based causal relationship.
- context related causes.
Explanatory analysis: ​
- variables
- relationships (+/- increase or decrease with variable)
- research population
- A conceptual model visualizes the relationship between variables.
- Independent variables influence a dependent variable.
WARNING
A conceptual model is different from a problem cluster. the model has variables instead of problems example: (research model): delivery speed
(problem cluster): slow delivery speed
Data Types:
Type | Name | Properties | Example |
---|---|---|---|
Qualitative | Nominal | data used for naming or labeling variables with no ranking | types of cars on the road |
Qualitative | Ordinal | categorical data with an order | grades (A, B, C, D, E, or F) |
Quantitative | Interval | operations(+,-), equal intervals between data points, 0 is arbitrary | temperature, with celsius 0 is arbitrary temperature can be negative |
Quantitative | Ratio | operations(+,-,*,/), equal intervals between data point, 0 is absolute, non negative | Height, cannot be negative |
Check if a relationship is causal:
- Sequence of events.
- Statistical relationship.
