There are 5 processes within the Application Maintenance and Renewal cluster. Within this cluster the majority of the work of Application Development is done. A major part of the work of Application Management deals with designing, programming and testing applications and information systems. [citation needed] Processes are: Impact analysis; Design
Cost estimation in software engineering is typically concerned with the financial spend on the effort to develop and test the software, this can also include requirements review, maintenance, training, managing and buying extra equipment, servers and software. Many methods have been developed for estimating software costs for a given project.

Over the lifetime of the product, software maintenance is estimated to comprise 75 percent or more of the total development cost. [ 36 ] [ 37 ] Completing a software project involves various forms of expertise, not just in software programmers but also testing, documentation writing, project management , graphic design , user experience , user ...
"Interest payments" are caused by both the necessary local maintenance and the absence of maintenance by other users of the project. Ongoing development in the upstream project can increase the cost of "paying off the debt" in the future. [clarification needed] One pays off the debt by simply completing the uncompleted work.

For example, a lean IT recommendation to introduce flexible staffing whereby application development and maintenance managers share personnel is often met with resistance by individual managers who may have relied on certain people for many years. Also, existing incentives and metrics may not align with the proposed staff sharing. [3] [36]
