We speak particularly plainly about two matters.
The advantages of open-architecture solutions, as compared to more closed platforms which lock you in. We have seen enough situations where client requirements evolve over time and users discover that the closed platform(s) do not readily rise to the new needs, and that the cost or complexity of deployment is actually prohibitive.
Relatedly, the business practices of technology vendors vary meaningfully. For example, OEMs that limit their relationship to the “integrator”, which makes the market less efficient for the end user. Open architecture does not necessarily mean efficient business practices.
