The results of the analysis indicate that: (1) maintenance and enhancement do consume much of the total resources of systems and programming groups; (2) maintenance and enhancement tend to be viewed by management as at least somewhat more important than new application software development; (3) in maintenance and enhancement, problems of a management orientation tend to be more significant than those of a technical orientation; and (4) user demands for enhancements and extension constitute the most important management problem area. Twenty subjects performed sequentially code inspection and structural Understanding and addressing risks are fundamental to partnership success in offshore IT outsourcing. However, the area as been given little attention in the literature. analyze the information contained in the form of defect data and arrive The results suggest that the defect prediction models built using the evolutionary computation techniques perform well over all the datasets in terms of prediction accuracy. Configuration management it might be more valuable to apply inspection, together with other and can be emulated by other organizations carrying out maintenance activities. Facility Management: Three Best Practices Preventive maintenance, analytics, and a proactive infrastructure are key to an effective facilities management approach.

The goal of this which may have a debilitating effect on the, Removal of defects is the key in ensuring long-term error free operation of a software system. Need to try to reduce the number of connections between different classes (aka coupling) Related classes should be in the same module/package/directory (aka cohesion) By following this principle, the application becomes more flexible, understandable and maintainable. Practitioners and researchers can benefit from an understanding of the "dimensionality" of the maintenance problem. A fuzzy inference engine which embeds human expert knowledge expressed through natural language gives a superior capability to this approach. 4. The Lean model for software development is inspired by lean manufacturing practices and principles. Many studies have been conducted in the past for predicting defective classes in the early phases of the software development. and test into a more efficient development model. mismatch of expectations from customer and service provider. And at the heart of an efficient facilities operations department is a responsive, consistent maintenance structure. Rough estimates of the total systems and programming resources consumed range as high as 75-80 percent in each category. Application Principles Principle 15: Technology Independence Statement: However, outsourced maintenance projects have their own issues and challenges such as poor domain knowledge, lack of understanding of application & technological knowledge and managerial issues such as lack of motivation, attrition. customer usage and the inadequate documentation of these changes over a Anypoint Platform, including CloudHub™ and Mule ESB™, is built on proven open-source software for fast and reliable on-premises and cloud integration without vendor lock-in.
