Choose around usage
A web application opens in a browser. A mobile application is usually distributed through a platform or device-specific channel. Start with the work to be done, usage frequency and user context.
Study real-world constraints
Are users always connected? Do they need photos, scanning or notifications? Do they use personal phones or managed devices? Each answer should become a testable requirement.
Separate the interface from the system
A web portal and a mobile application can share a backend. Catalogue, accounts, permissions and business records should not be unnecessarily duplicated. An API connects interfaces with rules and information.
Connect the application to business tools
If an order status comes from the ERP, define the information shown, read permissions, update frequency and behaviour when the connection fails. Existing access limits can influence architecture.
Start with a priority journey
Choose one useful task for one user: checking an order, recording a visit or submitting a document. A prototype tests understanding; a pilot tests actual usage, permissions and data exchanges.
Plan life after release
Include updates, monitoring, dependencies, distribution accounts and support. A working application at launch still needs an owner to keep it working.
