Re-usable program code documentation including the central repository feature allows CASE systems to share common program modules and documentation even storing of backups in case of emergency for example if a system failure unexpectedly occurs. On the contrary, failure to adequately control access to case repositories may result in security breaches or damages to the work documents, system designs or modules stored in the repository as backup.
An interactive workstation environment is encouraged by using CASE tools through the sharing of standardised product code structures among different companies. However inadequate standardization linking CASE tools from different software vendors (design tool from Company A, programming tool from Company B) may be difficult if the products do not use standardized code structures and data classifications. File formats can be converted, but usually not economically. Controls include using tools from the same software vendor, or using tools based on standard protocols and insisting on demonstrated compatibility. Additionally, if organizations obtain tools for only a portion of the development process, they should consider acquiring them from a software vendor that has a full line of products to ensure future compatibility if they add more
Resolving problems in organizations may be implemented by using the various CASE tools available for example project planning tools to resolve project matters. In contrast, unrealistic expectations may arise because organisations often implement CASE technologies to reduce development costs but implementing CASE strategies usually involves high start-up costs. Generally, management must be willing to accept a long-term payback period. Controls include requiring senior managers to define their purpose and strategies for implementing CASE technologies.
Technology also determines the use of CASE. If the firm is incapacitated for example an entity has insufficient computer capacity in certain departments the benefits derived from case cannot be fully realised as it requires an efficiently operating computer system with a server that co-ordinates the whole organisation.
