-The rapid development cycle consists of multiple iterations, where each iteration implements and tests one feature, that was defined during the preparation.
+The goal of the rapid development cycle is sequential implementation of the features in a system.

 \subsection{Preparation}
 Although the \ridm does not specify the complete steps for the preparation, it does state some requirements.
 The rapid development cycle requires a list of features that can be implemented one by one.
-These features are gained by splitting the system into individual subsystems, where each subsystem can be implemented and tested individually.
+These features are gained by partitioning the functionality of the system, such that features can be implemented and tested individually.
 For each feature it is required to specify the feature requirements and the corresponding test protocol.
 The feature requirements are based on the system requirements and the tests are used to validate that the feature meets its requirements.
 About the order of implementation, the \ridm states that critical features should be implemented first, as these features have an increased chance of invalidating the complete design.
