Definition

What is it?

Decision criteria are the important rules or conditions we use to choose between different options. They are like a checklist that helps us decide which choice is the best one for our goal.

Simple Example

Quick Example

Imagine you want to buy a new cricket bat. Your decision criteria might be: 'It must be lightweight,' 'It must be under ₹1000,' and 'It must be made of good quality wood.' You will check each bat against these rules.

Worked Example

Step-by-Step

PROBLEM: You need to choose a new school bag. Your parents said you can spend up to ₹800. You also want a bag that has at least 3 pockets and is waterproof.

Step 1: List your decision criteria.
- Price: Must be ₹800 or less.
- Pockets: Must have 3 or more pockets.
- Material: Must be waterproof.
---
Step 2: Look at Bag A. It costs ₹750, has 4 pockets, but is not waterproof.
- Price: Yes (₹750 <= ₹800)
- Pockets: Yes (4 >= 3)
- Material: No (Not waterproof)
---
Step 3: Look at Bag B. It costs ₹900, has 3 pockets, and is waterproof.
- Price: No (₹900 > ₹800)
- Pockets: Yes (3 >= 3)
- Material: Yes (Waterproof)
---
Step 4: Look at Bag C. It costs ₹600, has 5 pockets, and is waterproof.
- Price: Yes (₹600 <= ₹800)
- Pockets: Yes (5 >= 3)
- Material: Yes (Waterproof)
---
Step 5: Compare results. Bag A failed on waterproof. Bag B failed on price. Bag C met all criteria.

ANSWER: Bag C is the best choice because it meets all your decision criteria.

Why It Matters

Understanding decision criteria helps you make smart choices in life, big or small. In fields like AI/ML, computers use decision criteria to classify images or recommend products. Journalists use criteria to decide which news is important, and lawyers use them to build strong cases.

In the Real World
