I will be focusing on the elements of the system development process, the management controls I will be expecting to see throughout the process are:
-Authorisation required for development projects
-Changes must be controlled using appropriate approval and documentation
-Administrative controls must be built into the design of the new system (eg batch control supervisor), verification is normally done by checking a service or system meets a set of specifications. Verification procedures involve performing tests to model, then concluding a review of the modelling results. A verification usually repeat test to ensure the products continues to meet the specific requirements and complies with regulations that have been established during the beginning of the development process. Verification is an internal process and can be in development or production. Validation is intended to ensure that the product or system results in a system that meets the operational needs of the user. Validation is used to predict faults and gaps that might lead to invalid or incomplete verification of the product. This is mainly an external process. Security controls are to minimise or avoid security risks to any company or property; there are a number of ways to avoid this such as user login and access controls, firewalls and antivirus software.
-Documentation of developments must be complete, filed and kept up to date so that others can follow on
-User training to ensure they are able to make the most of the new system
-Scheduling of work and costs must be controlled to ensure a quality product is produced within budget and by the deadlines set
-Testing must be thorough and completed before approval for implementation
