Alfred Smart is a smart building management platform operating across multiple verticals: Home, Offices, Built-to-Rent, Hotels, and Parking. The product ecosystem consists of: 1) A tenant-facing mobile app for access control, climate management, bookings, and other building services. 2) An Assets Manager web platform for property managers. 3) An integrated IoT infrastructure including smart locks, climate sensors, consumption monitoring, and connected devices. Each vertical involves different stakeholders, unique use cases and user journeys, variable occupancy cycles and different levels of operational complexity. The challenge was not about designing isolated features for each vertical, it was transforming an existing technology foundation into a cohesive product system capable of scaling across different business models. The main structural challenges were: - Inconsistent experiences across verticals. - Design decisions driven by short-term business needs rather than a scalable product strategy. - Lack of a clear framework to define what should remain core and what should be adapted per vertical. - Increasing development complexity caused by accumulated product inconsistencies.
