# How do I validate the effectiveness of a feature?

I use the below tools in my work to manage analytics:

1. Google Analytics
    
2. Tealium
    
3. Firebase
    

# What did I like about Google Analytics?

1. It's interactiveness
    
2. The user segmentation
    

# How does it help me?

1. Form a hypothesis.
    
2. Frame it as a question to validate the hypothesis
    
3. Create relevant user segmentation and validate the events
    

### Example:

#### Hypothesis

The % of successful signup is 100 on Mobile devices

#### Question

Do mobile users have 100% successful signups?

#### How do I test it?

1. Create a user segment of mobile devices - With varied parameters given below
    
    1. App
        
    2. Device Brand name
        
    3. Exclude vs Include
        
2. Add a secondary dimension if required to look for a specific bunch of events
    
    1. The event starts/contains with "signup"
