A location-based app looks like a map with pins. Behind the map, the workflow decides how often the app needs a position, what happens when it can't get one and what the map provider bills. Highlights * Positioning choice trades accuracy for battery, so settle it before design. * Background location rules differ on iOS and Android, so test permissions on both. * Map providers bill on different units, so compare them at target volume.

Manual handoffs grow faster than headcount. Here's how workflow automation works, what to automate first and when no-code tools stop being enough. Highlights * Simplify a process before workflow automation locks in every step. * Pilot only processes with an owner, a baseline and an exception path. * Choose no-code, a platform or custom code by data, logic and recovery needs.

Your Ruby on Rails backend keeps pace with the roadmap until open connections start driving your server count. This guide helps you judge whether an Elixir service would fix that bottleneck or Ruby can still carry it. Highlights * Elixir earns its place when open connections drive your server count. * Rails remains a strong fit for CRUD work when your team already ships Ruby. * A separate Elixir service pays off only for a measured, isolated bottleneck.

An agreed specification gives your team a shared basis for estimates and acceptance tests. Here's how to write a software requirements specification your development partner can price, build and verify. Highlights * An SRS turns business goals into requirements a team can estimate and test. * Testable criteria and mapped integrations make an estimate defensible. * Mobile apps add store rules, OS targets, offline behavior and privacy disclosures.

Your EHR holds the clinical record, and your product supports the workflows around it. This guide shows when to configure the EHR system you run, when to extend it through FHIR and when to build. Highlights * For customers using Epic, a module can add your workflow while Epic keeps the record. * Integrations and certification scope move budget and timeline more than screens do. * HIPAA safeguards, audit trails and BAAs belong in the architecture before code.

Your CRM worked for your first sales team; now part of the pipeline lives in side spreadsheets. Here's how to decide whether a custom CRM pays off and what building one takes. Highlights * Measure what CRM workarounds cost before you treat them as a reason to build. * Compare both options over 36 months and count migration and integrations once in each. * Plan for scope, integration and adoption risks before the first sprint.
