If you’re considering the technology in your spaces or looking into creating a smart building, you may have heard of the term MSI, or Master Systems Integrator.

But like many of the terms in our industry, it is often used loosely or incorrectly. We’re on a mission to educate property professionals on the true role of an MSI and set the standard for what one should provide.

An MSI is the organisation that integrates all of the technical systems within a building, enabling all of the separate pieces to work together seamlessly. The Navigant Consulting (now Guidehouse) description of an MSI is one which we think fits us perfectly.

A service provider that demonstrates domain expertise in IT systems and networking, building automation and controls, application software analytics, and support services. An MSI can create and program cross-system integration with complete interoperability. 

As part of our mission as a B Corp to educate the industries we serve and lead the way in creating the guidelines of best practice for others to follow, we’ve created several pieces of content which you can download for free to understand more about the role of an MSI and how it could help you.

Our Manifesto

  1. We acknowledge the breadth of personas that exist within all building ecosystems – landlords, tenants, employees, visitors, building operators and facilities managers.
  2. We define requirements first, gaining an understanding of what people need to achieve and their jobs to be done before making choices on technologies and systems.
  3. We prioritise achieving exceptional user experiences for all personas over single vendor convenience through thoughtful design, procurement, construction and building operation.
  4. We use best of breed technologies, selecting products and systems with the ability to be part of and integrate into a wider ecosystem using open protocols.
  5. We acknowledge that the use of any building as well as floors and spaces within it will change in use over time. Technology and systems should facilitate changes and on-going optimisation, being as inexpensive as possible in achieving these goals.
  6. We don’t lock people into vendor relationships and expect any vendors engaged to provide consumption-based pricing (no long-term contracts) and complete data portability.
  7. Whilst the use of cloud technologies may feature in the overall technology architecture, all data and systems control will primarily occur in and ultimately be owned by the physical building to ensure continued operation during any connectivity interruption or service outage.
  8. Data and people’s privacy are treated with respect, particularly where information is personally identifiable. ‘Opt-in’ rather than ‘default-in’ is our recommended method of engaging people. All data is fully encrypted both at rest and in transit as far as is practically possible.
  9. We perform failure mode analysis at all levels – devices, area/field, supervisory control, overall systems architecture and user interfaces, ensuring this is documented and gracefully handled where possible.

Our projects

Vanti have worked on a huge range of projects for a wide variety of organisations. Here are just a few of the clients we’ve helped to get the most out of their spaces by using innovative technology and a forward-thinking approach.
