Quantitative software measurement extends significant benefits to IT organizations. Relatively few successful, robust, and mature measurement frameworks have been implemented. In response to the pandemic, plenty of organizations had to re-invent themselves or significantly change the way they do business.
Software Maintenance Cost Resources » Resources » Software Maintenance Cost The need to monitor maintenance costs most common mistake young tech entrepreneurs make is to drastically underestimate the amount of money spent on software.
Basic cost breakdown The entire process of software maintenance involves many moving parts with varying degrees of complexity and resource requirements and hence different costs. Factors that affect software maintenance costs A lot of real-world factors can lead to a fluctuation in software maintenance costs.
Ways to cut down software maintenance costs DevOps is a highly effective programming method that helps in minimizing maintenance costs. New projects may be added by using pre-existing project entries and defining new or modifying existing work elements. Powered by a pop-up wizard which guides users through the process of defining project scope and complexity and identifying what resources are required. Simulation and Modeling Engine — leading, state-of-the-art modeling tools derived from a very wide ranging database of project histories, key metrics and behavorial models.

The number of input and output values then provides an indication of the number of functions the software supports.
Albrecht also postulated that the unadjusted function points UFP are dependent on the number of inquiries, files, and interfaces the software uses. The following equation shows this relationship for modern software:.
This equation is a weighted sum of these five characteristics, meaning the factor associated with each characteristic indicates its relative importance. For example, the number of interfaces has a factor of 10, so this characteristic is twice as important as the number of outputs, which has a factor of only 5.
Researchers have validated these weights over many projects. A group of related data items counts as one input, rather than an individual data item. Assume for this example that an employee payroll application requires employee data as input, including items like name, address, and phone number. This group of items would likely be considered as one input since they all pertain to the same employee. Each output is a single printed report, screen display, or error message.
As with inputs, a group of related data items counts as only one output. Inquiries are distinct interactive queries from the user. They consist of user commands requiring a response from the software. Each logical file that the software uses counts as a file. These files contain logically related data so they may be physical files or data structures.
An interface must exchange information with other systems to be counted. They include communication links and physical media. The TCF requires you to assign a rating on each of the following 14 influencing factors:. The rating scale for these influencing factors ranges from 0 for no influence at all to 5 for essential.
These scores are then totaled to provide a Degree of Influence DI score ranging from 0 to The TCF can then be calculated as 0. The next step in the COCOMO formula is calculating the effort adjustment factor EAF , which requires you rate the importance of 15 cost drivers in four attribute categories. The attribute categories include product, hardware, personnel, and project. The rating scale for each cost driver has six levels, including very low, low, nominal, high, very high, and extra high.
Each of these levels has an associated value known as an effort multiplier for each driver, which generally ranges from 0. The following table shows these effort multipliers:. Multiply the effort multipliers together to obtain the EAF.
The following equation will then provide the effort needed to develop the software:. The values a and b depend on the type of software project as follows:. Once you have estimated the total effort needed to develop the software, you can allocate that effort among the team members. Add these costs for each team member to obtain the total cost of effort for the project. For example, an ACT of 0.
Multiply the ACT by the total development cost to estimate the annual maintenance cost. Easy Normal Medium Hard Expert. Writing code in comment? Please use ide. Load Comments. What's New. Most popular in Software Engineering. More related articles in Software Engineering.
