Write the job description first
Describe what the device needs to accomplish in ordinary language. This becomes the filter for every specification and sales pitch. If a feature does not improve one of the jobs, it may not deserve part of the budget.
Separate needs, preferences, and extras
A required feature determines whether the product works at all. A preference makes it pleasant. An extra may be interesting but does not change the result. Include accessibility, comfort, screen clarity, weight, battery life, and interface complexity.
- Must work with existing devices or software
- Must fit the available space or travel need
- Should be comfortable and easy to understand
- Nice to have only if the price difference is reasonable
Check the costs that arrive after checkout
The shelf price may not include a mount, adapter, storage, subscription, installation, case, warranty, data plan, ink, or replacement accessories. Check software and security support too.
Protect compatibility before chasing performance
Confirm ports, operating systems, app support, wireless standards, account requirements, and physical dimensions. Include every household member who needs to use the product.
Compare three useful levels
Compare the least expensive choice that meets the requirements, the best-value choice with meaningful improvements, and a premium option that shows what extra spending actually buys. Premium becomes overbuying when the added capabilities do not serve the job description.
