COM606 Software Process Engineering and on the Portal Introduction

Engineering The application of knowledge to practical uses such as the design of structures, machines, and systems. Engineering has many specialities such as civil engineering, chemical engineering, mechanical engineering and software engineering.

Software Systems Engineering “The systematic application of scientific and technological knowledge, through the medium of sound engineering principles, to the production of computer programs, and to the requirements definition, functional specification, design description, program implementation, and test methods that lead up to this code”.

Computer Programs This is what we are applying our knowledge to. A computer program is simply a product of the software engineering process. A product is a work product that is intended for delivery to a customer or end-user. A product can take different forms. A product can be a process or a service. A work product is a useful result of a process (an engineering process) and can take the form of files, documents, products, services, processes.

Requirements definition, functional specification, design description, program implementation, and test methods By our earlier definition we are applying our knowledge to the production of computer programs and the use of the activities identified above. These activities have been conveniently arranged for us in what we call a development lifecycle. Engineers use development lifecycles to guide them in the activities necessary to build a product

Software Process SDLC does not tell us how to do anything. It informs us of the type of activity to be engaged in and the order of such activities. When we choose a lifecycle for development and decide how we are going to carry out the necessary activities we have a software process (sometimes referred to as a software development methodology). Unfortunately, the industry has confused these many terms. Sometimes a SDLC is referred to as a software process. A software process, however, employs specific practices, tools and techniques with which to carry out the activities identified in a SDLC. The SDLC is not specific about this.

Process Performance Models It is organisations that use software processes in their everyday development of software products and processes. Models exist which identify the type of processes and practices which are necessary in a capable process Organisations can then examine the software processes that they are using and compare these with the processes shown in the model This can then reassure the organisation that its processes are capable Such models are the CMMI-DEV, SPICE and ISO15504 to name just a few
