Managers follow a systematic process to make correct decisions.

Reference books (Laudon & Laudon, Goyal, Jawadekar) classify decision-making into steps.

🪜 3.1 Steps in Decision Making

(Write these in exam!)

⭐ 1. Problem Identification

You first recognize that a problem exists.

Examples:

Sales declining
Too much customer complaints
High employee turnover
Inventory shortage

👉 Without identifying the problem correctly, the solution will be wrong.

⭐ 2. Data Collection

Collect data related to the problem.

Examples:

Sales report
Customer feedback
Production report
Market trends

👉 THIS is where computers help by storing and retrieving data quickly.

⭐ 3. Identify Alternatives

Different possible solutions.

Examples:
For sales drop → solutions may be:

Reduce price
Increase advertising
Launch new product
Improve quality

⭐ 4. Evaluate Alternatives

Compare the alternatives using:

Cost
Profit
Time
Risk
Resources

Managers check pros & cons of each option.

⭐ 5. Choose the Best Alternative

This is actual decision making.

Example:
“Reduce price by 10% + increase digital ads.”

⭐ 6. Implement the Decision

Put the chosen solution into action.

Example:
Launch new pricing strategy → start advertising.

⭐ 7. Review & Feedback

Check results.

Example:
After 3 months → Did sales increase?
