What is maintenance?

Operational Maintenance is one of the significant phases in the life cycle of a software product in operation. Software operational maintenance involves improving, optimizing and eliminating software defects or bugs as well as ensuring stabilization after delivery.

The life cycle standard IEEE 12207 and the International Standard ISO/IEC 14764 (Standard for Software Engineering - Software Maintenance) position Maintenance as one of the main processes in the software development life cycle (SDLC).

Our goal at APIBEST is to see that your software continues to function at best and remain relevant even with changing times and business operations.

There are four main types of software maintenance any business can need

Corrective maintenance is a responsive modification of a software product performed after delivery to correct any discovered problem.

Adaptive maintenance

Adaptive Maintenance involves the modification of your software product after delivery to ensure that your software product remains useful in a changed or changing environment.

Improving maintenance

Improving Maintenance addresses concerns with the modification of a software product after delivery to improve its performance or maintainability.

Preventive maintenance handles the inspection and modification of a software product after delivery to detect and correct latent faults in the software product before they become effective faults.
