Techniques Flashcards
What is Benchmarking technique?
Benchmark studies are performed to compare the strengths and weaknesses of an organization against its peers and competitors.
Benchmarking is usually focused on strategies, operations and processes.
What is the disadvantage of Benchmarking?
Because it involves assessing solutions that have been shown to work elsewhere, with the goal of reproducing them, benchmarking cannot produce innovative solutions or solutions that will produce a sustainable competitive advantage.
What is a business rule?
A business rule is a specific, actionable, testable directive that is under the control of an organization and that supports a business policy.
How BABOK defines business policy?
A business policy is a non-actionable directive that supports a business goal.
What is “term and fact model”?
a defined glossary of terms and an understanding of the relationships between them.
Related to Data Dictionary and Glossary (9.5) and Data Modeling (9.7)
What are structure rules?
Structural rules state something is or is not true. It may also describe how information may be inferred or calculated based on other data available to the business.
They cannot be violated (but they can be misapplied).
What is data dictionary and glossary?
A data dictionary or glossary defines key terms and data relevant to a business domain.
What does data dictionary includes?
A data dictionary includes standard definitions of data elements, their meanings, and allowable values.
A data dictionary contains definitions of each primitive data element and indicates how those elements combine into composite data elements.
What information must be recorded about each primitive data element in the data dictionary?
- Name
- Aliases: alternate names for the data element used by various stakeholders.
- Values/Meanings
- Description
What is the structure of Composite data in the data dictionary?
Composite data is assembled from primitive data elements. Composite structures include:
- Sequences
- Repetitions
- Optional Elements
What is data modelling techniques?
The purpose of a data model is to describe the concepts relevant to a domain, the relationships between those concepts, and information associated with them.
The two most widely used types of data model are the entity-relationship diagram (ERD) and the class diagram, although other modeling notations remain in use.
What is Analogous Estimation?
Analogous estimating is often used to develop a rough order of magnitude (ROM) estimate, and is also known as “top-down” estimating. This is usually done at the beginning of the project or project phase and more detailed estimates follow as more is known.
What is Bottom-up Estimation?
Using Bottom-up Estimation technique the business analyst has collected the deliverables, activities, tasks, and estimates from all the involved stakeholders and rolls them up to get a total for all the activities and tasks.
What is Rolling Wave estimation?
Rolling Wave technique involves refinement of estimates. Estimate the details for activities in the current iteration or increment and provide an analogous estimate for the entire scope of work.
What is Three-point Estimation?
Three-point Estimation is used in Uses scenarios:
The most optimistic estimate, or best-case scenario
The most pessimistic estimate, or worst-case scenario
The most likely estimate
What is Delphi estimation?
Delphi estimation uses a combination of expert judgment and history. There are several variations on this process, but they all include individual estimates, sharing the estimates with experts, and having several rounds until consensus is reached. An average of the three estimates is used.
What is the disadvantage of Interface Analysis?
Does not provide insight into other aspects of the solution since the analysis does not assess the internal components.
What is the disadvantage of Interview?
Interviews are not an ideal means of reaching consensus across a group of stakeholders.
