Manageability is most important during the second half of a System Lifecycle phases (i.e. operation, maintenance, support). Manageability can greatly influence the recurring costs and can increase the chances of a failure. Often a system that hard to manage is described as fragile since the smallest of changes can have dire consequences on the systems functionality.

Manageability directly influences a system's reliability, availability, security, and safety, thus being a key ingredient of system dependability.

Just like security and safety, manageability is generally hard to retrofit in complex systems—it is always easier to build it in from day one. However, in the absence of means to measure manageability and to quantify the various tradeoffs, it is difficult to get the design right. We proposed a manageability metric that combines management workloads and weightings based on real world studies with direct measurement of the number of steps involved in management tasks and their duration. ¹⁾

Data Distribution Service (DDS) can not solve all of a systems(or projects) Maintainability issues, however, by DDS's design, it can eliminate or reduce the Manageability issues that could arrise from using DDS.
