Business Analysis Techniques (K Level 4/5) Flashcards
(128 cards)
Use Quantitative Techniques When:
Measurable Data is Required
Testing Hypotheses
Use Qualitative Techniques When:
In-Depth Understanding: allow a deeper, contextual understanding of a business situation.
Complex and Unstructured Data: If your data is complex, unstructured, or difficult to quantify, qualitative methods, such as interviews, focus groups, or content analysis, may be more appropriate.
Subjective Perspectives: If you want to capture subjective perspectives, opinions, and individual experiences,
Why would an as in business process model alone not be a sufficiently document the business system
an ‘As-is’ business process model may be a supplementary technique but
would not provide sufficient information to document the entire
business situation
Interview uses
- Fact finding (business situation and actors role in it)
- Understand perspective
- Stakeholder engagement
- Business overview
- Elicit requirements
Interview process
Successful interview has 3 main stages
- Prep & planning - who? why? what info do I know? where?
- Interview - closed/open/leading questions & build rapport
- Follow up - document & circulate output
Interview advantages and disadvantages
Advantages:
- Builds relationships
- Understand perspectives
- Confidential
- Yield important information
Disadvantages:
- Time consuming (both parties)
- info elicited is based on opinion (quantitative confirmation may be required)
- only one view point
What is an interview
A structured discussion between the analyst and a stakeholder to elicit facts and information about the business situation and their role in it.
What is a workshop
A forum where a selected group of SH participate in a facilitated discussion to achieve an agreed objective
Workshop - uses
- Agree direction/scope of project
- Discuss conflicting perspectives
- Elicit & agree requirements
- Examine possible solutions
Roles in a workshop
Participants
Scribe
Facilitator
Techniques to support workshops
Icebreaker
Round robin
Brainstorming techniques
Workshop process
- Planning & prep: objectives/attendees/venue etc
- Conduct: focus on objectives/ensure participation/summarise key points
3.Follow up: Document & circulate output/invite feedback
Workshop advantages and disadvantages
Advantages:
- Fast
- Stakeholders involved and feel ownership
- Simple method of resolving issues
- More creative solutions produced
Disadvantages:
- Group dynamics need to be carefully managed
- Hidden agendas
- Hard to organise
- Authority limitations
What is observation
Watch actors carry out their work
3 Types of Observation
Formal Observation
- Watching specified tasks
- Staff are prepared
- May see only what they want you to see (potential disadvantage)
Informal Observation
- No staff preparation
- May not see all required tasks being performed
-Shadowing
- Following a user for period of time
- May include protocol analysis (talk me through whilst doing it)
Good for uncovering tacit knowledge
Observation Advantages/Disadvantages
Advantages:
1. We can get a good understanding of the processes, problems, politics etc
2. Helps devise workable, acceptable solutions
3. Helps with follow up questions
Disadvantages:
1. Can feel like ‘Big Brother’ – unsettles the observed
2. Your presence may impact the process
What is scenario analysis?
Telling the story of the task, including:
1. All steps from business trigger to outcome
2. Pre-conditions
Must be true for the scenario to begin
3. Post-conditions
Must be true following conclusion
4. Alternative paths
5. Exception situations
(deeper dive to process mapping)
Scenario Analysis Advantages/Disadvantages
Advantages
- Aids visualisation and discussion of real life situations
- Can be used to build test scenarios
Disadvantages
- Can become complex, especially where many alternative paths
- Time consuming
Document analysis
Reviewing and analysing source documentation such as forms, screen layouts and reports to uncover info about the organisation/process/system
What is a powerful supplementary technique
Document analysis
Document Analysis Advantages/Disadvantages
Advantages
1. Can yield good information on Organisation/Process/System
Disadvantages
1. Don’t get differing viewpoints
2. Dry & Tedious
What to consider when identifying an appropriate technique?
Agile/Linear (detail vs outlines)
Time
Documentation styles
Stakeholder availability
Business preference
Ability to repeat & revisit
Quantitative technique
Surveys/questionnaire
Surveys/questionnaire - uses
Gather information when other techniques e.g. workshops as the population is too large or disperse
Cultural reasons - a membership organisation where consultation is expected
Gain validation from a large group of people
Quantitative data is needed
