💡 Hint

Common Mistakes

Choosing weaknesses instead of strengths

Confusing opportunities with threats

SWOT analysis identifies strengths and threats among other factors to find risks.

5fill in blank

hard

Fill all three blanks to complete the code describing a technique that uses historical data and expert input.

Software Engineering

💡 Hint

Common Mistakes

Choosing Delphi which is expert-only

Selecting qualitative which is not listed

The quantitative technique uses historical data and expert opinions to identify and measure risks.

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
