# Mandatory Base, Platform, Suites & Modules

ABB Ability™ BuildingPro Suites is built around a layered architecture that gives you full control over what you deploy and how you grow. Every deployment starts from the same mandatory foundation, and everything above it is assembled to match your specific needs.

There are three core concepts to understand:

* **Mandatory Base** — the foundation included in every deployment, providing connectivity, asset modeling, user management, and governance. Without it, nothing else runs.
* **Platform** — a comprehensive solution that unlocks the full capabilities of BuildingPro Suites, giving teams and integrators the complete toolbox to build tailored smart building solutions.
* **Suites and Modules** — outcome-focused packages that deliver measurable results in specific domains such as energy, occupant comfort, operations, and more. Each Suite contains Modules that address concrete use cases.

## How It Fits Together

Think of it like building with blocks. The Mandatory Base is always the foundation,  it is included in every deployment and cannot be removed. On top of it, you choose your path:

* Choose **Platform** if you need the full toolbox and maximum flexibility to build, extend, and customize your solution across any building type or portfolio.
* Choose **Suites and Modules** if you want to go live fast with defined, outcome-focused packages tailored to specific domains, and expand gradually.

Both approaches can be combined. Platform and Suite modules are complementary, not mutually exclusive.
