Software Design & Implementation Activity:

The implementation stage of software development is the process of converting a system specification into an executable system. A software design is a description of the structure of the software to be implemented, the data which is part of the system, the interfaces between system components and, sometimes, the algorithms used. Designers design step by step to meet the finished design to be implemented in programming to crease an executable system out of the specification.

Software Specification:

Software specification or requirements engineering is one of the four activities of software process. In software specification, the task is to identifying and defining the services to be provided from the system and what are the constraints in the operations of the system and in the development of the system. This stage, among the four activities of software process, is critical enough as this is the first stage of the process and defines the whole system. Missing or misunderstanding requirements, leaving gaps or errors will ultimately cause higher development cost, time and rework.
