It is a common practice for aviation companies to use multiple applications to manage their operations; whether custom-built, acquired from a third-party, part of a legacy system, or a combination thereof. Often, such applications have limited interfaces necessitating duplicate data entry – a recipe for inducing errors and decreasing efficiency. Even when interfaces exist, they can be difficult to manage and require resources to build, maintain, and support them.

MISA provides the solution for these issues by standardizing, streamlining, and integrating business processes across all the various departments and functional areas within the company; and this integration improves the bottom line while providing employees a user-friendly and consistent application experience across the whole organization.
