Risk identification techniques in Software Engineering - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of risk identification in project management?

Risk identification is the process of finding and listing potential problems or threats that could affect a project. It helps teams prepare and plan to reduce negative impacts.

beginner

Name two common techniques used for risk identification.

Two common techniques are brainstorming, where team members share ideas freely, and checklists, which use a list of known risks to review potential issues.

intermediate

How does SWOT analysis help in risk identification?

SWOT analysis looks at Strengths, Weaknesses, Opportunities, and Threats. It helps identify risks by focusing on Weaknesses and Threats that could harm the project.

intermediate

What role do expert interviews play in risk identification?

Expert interviews involve talking to experienced people to uncover risks that might not be obvious. Their knowledge helps find hidden or complex risks early.

beginner

Why is documentation review important in risk identification?

Reviewing project documents like plans and contracts helps spot inconsistencies or missing information that could lead to risks. It ensures nothing is overlooked.

Which technique involves gathering ideas from a group to identify risks?

A Expert interviews

B SWOT analysis

C Documentation review

D Brainstorming

Brainstorming encourages open sharing of ideas from team members to find possible risks.

What does SWOT stand for in risk identification?

A Strengths, Weaknesses, Opportunities, Threats

B Strategy, Work, Objectives, Timing

C Systems, Workflow, Operations, Testing

D Skills, Workload, Options, Targets

SWOT stands for Strengths, Weaknesses, Opportunities, and Threats, used to analyze risks.

Which risk identification technique uses a prepared list of known risks?

A Checklists

B Expert interviews

C Brainstorming

D SWOT analysis

Checklists use a list of known risks to help identify potential issues.

Why are expert interviews useful in risk identification?

A They provide detailed project schedules

B They help find hidden or complex risks

C They replace the need for documentation

D They finalize the project budget

Experts share knowledge that helps uncover risks not obvious to others.

What is the main goal of reviewing project documents for risk identification?

A To create the project timeline

B To assign tasks to team members

C To find missing or inconsistent information that could cause risks

D To approve the project budget

Reviewing documents helps spot gaps or errors that might lead to risks.

Explain three different techniques used to identify risks in a project.

Think about group discussions, lists, analyzing strengths and threats, consulting experts, and reading project papers.

Why is it important to identify risks early in a project? How do risk identification techniques help?

Consider how knowing risks early can save time and money.

Practice

1. Which of the following is a common technique used for risk identification in software engineering?

easy

A. Version control

B. Code compilation

C. Unit testing

D. Brainstorming

Solution

1. Step 1: Understand risk identification purpose

   Risk identification techniques help find potential problems early in a project.

2. Step 2: Match technique to risk identification

   Brainstorming is a method where team members suggest possible risks, making it a common technique for risk identification.

3. Final Answer:

   Brainstorming -> Option D

4. Quick Check:

   Brainstorming = Risk identification technique [OK]

Hint: Brainstorming is a go-to method for spotting risks early [OK]

Common Mistakes:

• Confusing testing or coding tasks with risk identification
• Thinking version control helps identify risks directly
• Assuming unit testing finds risks instead of bugs

2. Which syntax correctly lists a risk identification technique in a checklist format?

easy

A. - Brainstorming
- Interviews
- SWOT analysis

B. Brainstorming Interviews SWOT analysis

C. [Brainstorming, Interviews, SWOT analysis]

D. Brainstorming; Interviews; SWOT analysis;

Solution

1. Step 1: Identify proper checklist format

   A checklist uses clear bullet points or dashes to list items line by line.

2. Step 2: Compare options

   - Brainstorming - Interviews - SWOT analysis uses dashes and new lines, which is a correct checklist style. Others are either plain text or incorrect separators.

3. Final Answer:

   - Brainstorming - Interviews - SWOT analysis -> Option A

4. Quick Check:

   Checklist format = - Brainstorming - Interviews - SWOT analysis [OK]

Hint: Checklists use dashes or bullets with line breaks [OK]

Common Mistakes:

• Listing items without separators or line breaks
• Using commas or semicolons without clear formatting
• Confusing array notation with checklist style

3. Consider this code snippet representing risk identification methods in a list:

methods = ['Brainstorming', 'Checklists', 'Interviews', 'SWOT']
print(methods[2])

What will be the output?

medium

A. Brainstorming

B. Checklists

C. Interviews

D. SWOT

Solution

1. Step 1: Understand list indexing

   In Python, list indexes start at 0, so methods[0] = 'Brainstorming', methods[1] = 'Checklists', methods[2] = 'Interviews'.

2. Step 2: Identify the printed element

   The code prints methods[2], which is 'Interviews'.

3. Final Answer:

   Interviews -> Option C

4. Quick Check:

   methods[2] = Interviews [OK]

Hint: Remember Python lists start at zero index [OK]

Common Mistakes:

• Assuming list starts at 1 instead of 0
• Confusing the order of items in the list
• Mixing up the index number with the value

4. This code attempts to add a new risk identification technique to a list but causes an error:

methods = ['Brainstorming', 'Checklists']
methods.add('Interviews')

What is the error and how to fix it?

medium

A. TypeError; convert list to set first

B. AttributeError; use methods.append('Interviews') instead

C. SyntaxError; add parentheses to methods.add()

D. No error; code runs fine

Solution

1. Step 1: Identify the error type

   Lists in Python do not have an 'add' method, so calling methods.add() causes AttributeError.

2. Step 2: Correct method to add item to list

   To add an item to a list, use methods.append('Interviews').

3. Final Answer:

   AttributeError; use methods.append('Interviews') instead -> Option B

4. Quick Check:

   List add method error fixed by append() [OK]

Hint: Use append() to add items to lists, not add() [OK]

Common Mistakes:

• Using add() on lists instead of append()
• Thinking add() works like append() for lists
• Ignoring error messages and assuming code runs

5. You want to identify risks in a new software project. Which combination of techniques will give the most thorough risk identification?

hard

A. Brainstorming, Checklists, Interviews, and SWOT analysis combined

B. Checklists and Interviews only

C. Brainstorming only

D. SWOT analysis only

Solution

1. Step 1: Understand benefits of multiple techniques

   Using several risk identification methods together helps find more risks by covering different perspectives.

2. Step 2: Evaluate options

   Brainstorming, Checklists, Interviews, and SWOT analysis combined combines brainstorming, checklists, interviews, and SWOT analysis, providing a comprehensive approach.

3. Final Answer:

   Brainstorming, Checklists, Interviews, and SWOT analysis combined -> Option A

4. Quick Check:

   Multiple techniques combined = best risk identification [OK]

Hint: Combine techniques for best risk coverage [OK]

Common Mistakes:

• Relying on only one technique
• Ignoring SWOT analysis benefits
• Thinking checklists alone find all risks
