[Use] The Activity Checklist

Please refer to the [Study] The Activity Checklist for the theory.

It is time for me to use this checklist for evaluating the Supermarket Self-checkout system using Evaluation Version Checklist

1. Means/Ends:

People who use the target tech.:

• Sellers (Supermarket staffs)
• Buyers (Children/ Adults, Girls/ Boys, Young/ Old People, Local/ Foreign People)
• Maintenance staffs

Goals and subgoals of the target actions:

• To help the checkout process faster, therefore reducing waiting time of the customer
• To reduce human resource of checkout process therefore reduce costs
• To be correct in the price calculation of the checkout items
• To avoid items stolen

Criteria for success or failure of achieving target goals

• Self - checkout process must be simple enough and easy to use 
• Ensuring completeness and accuracy of checkout items
• Must be significantly faster than using tradition checkout method
• Must be cheaper than hiring staff in long-term

Potential conflicts between goals

• The completeness cannot be fully ensured using self-check out system due to customer can illegally not put the items into the check-out system. With staffs, they can check completeness more carefully
• The self-check process can only be faster if it is easy to use with all types of customer
• The cost of the entire self-check system may be more expensive than hiring staff.

2. Environment:

Role of target technology in producing the outcomes of target actions

• Replace the staffs for checkout process

Tools, other than targeted technology, available to users

• Checkout staffs
• RFID technology
• Online shopping

Integration of target technology with other tools

• The scanned machine
• The card payment/ cash payment systems
• The gate that checks un-payed items
• Security guard 

Rules, norms, and procedures regulating social interactions and coordination related to the use of target technology

• The self-check out system heavily relies on the people self-awareness of illegal actions. Some countries, where the rate of items being stolen is very high, cannot apply these systems without increasing of guards
• Besides, knowledge and technology required for normal user to use these systems (debit/credit cards, how to use electronic devices) will not be the same for any countries especially developing countries.

3. Learning/Cognition/Articulation

Knowledge about target technology that resides in the environment and the way this knowledge is distributed and accessed

• Sellers (Supermarket staffs) -> interview, observation
• Buyers (Children/ Adults, Girls/ Boys, Young/ Old People, Local/ Foreign People)  -> interview, observation
• Maintenance staffs  -> interview, observation

4. Development

This phase will not be considered for this existing self-checkout system and for the homework as well.
