Summary of the Article – Why is Software Maintenance Expensive?
1. Software maintenance costs make up 75% of TCO. Unlike physical products, software does not wear out but becomes less useful over time. This, along with inherent issues within the software, contributes to the expenses of maintenance.
2. The average cost of software maintenance services is 20-25% of the license cost per year. However, the exact amount depends on various factors such as hiring dedicated software developers, which can range from $25 to $120 per hour.
3. Complexity of the software affects maintenance costs. More complex software requires more enhancements and other maintenance activities, resulting in higher costs. Surveys indicate that maintenance costs as a percentage of build costs can range from 40% to over 90%.
4. Several software-end factors influence maintenance costs:
- Structure of the software program: The organization and architecture of the program contribute to the complexity of maintenance.
- Programming language: Different programming languages may have varying maintenance costs due to factors such as availability of skilled developers.
- Dependence on external environment: Software that relies heavily on external systems or platforms may require more maintenance to adapt to changes in those environments.
- Staff reliability and availability: The reliability and availability of the development team can impact the efficiency and cost of software maintenance.
5. Software maintenance is challenging due to the following reasons:
- Lack of traceability: Codes are often not traceable to the original requirements and design specifications, making it difficult for programmers to detect and correct defects.
- Key maintenance issues: Both managerial and technical issues contribute to maintenance difficulties. Managerial issues include aligning with customer priorities, staffing, assigning responsibilities, and estimating costs. Technical issues include limited understanding, impact analysis, testing, and maintainability measurement.
15 Questions Based on the Text:
1. Why are software maintenance costs high? Software maintenance costs are high because the software becomes less useful over time and issues arise within the software itself.
2. What percentage of TCO do software maintenance costs typically form? Software maintenance costs typically form 75% of TCO.
3. How much do software maintenance services cost on average? On average, software maintenance services cost around 20-25% of the license cost per year.
4. What factors influence the cost of software maintenance? Factors influencing the cost of software maintenance include the complexity of the software, the programming language used, dependence on external environments, and staff reliability and availability.
5. Why does the complexity of software affect maintenance costs? More complex software requires more enhancements and maintenance activities, resulting in higher costs.
6. What are the software-end factors that affect maintenance costs? The structure of the software program, programming language, dependence on external environment, and staff reliability and availability are software-end factors influencing maintenance costs.
7. Why is software maintenance difficult? Software maintenance is difficult because codes are often not traceable to the requirements and design specifications, making it challenging to detect and correct defects.
8. What are the key issues in software maintenance? The key issues in software maintenance include alignment with customer priorities, staffing, assigning responsibilities, estimating costs, limited understanding, impact analysis, testing, and maintainability measurement.
9. Why does software maintenance require detective-like work? Software maintenance requires detective-like work because programmers need to pore over the program, looking for clues to detect and correct critical defects affecting customer operations.
10. Which factor has the most significant impact on software maintenance costs? The complexity of the software has the most significant impact on software maintenance costs.
11. What are the challenges with traceability in software maintenance? Codes are often not traceable to the requirements and design specifications, making it difficult to detect and correct defects in software maintenance.
12. How does management contribute to software maintenance difficulties? Management contributes to software maintenance difficulties through issues such as alignment with customer priorities, staffing, assigning responsibilities, and estimating costs.
13. What are the technical challenges in software maintenance? Technical challenges in software maintenance include limited understanding of the code, impact analysis, testing, and measuring maintainability.
14. How does programming language affect software maintenance costs? Different programming languages may have varying maintenance costs due to factors such as the availability of skilled developers.
15. Why do software maintenance costs increase as the software gets older? Software maintenance costs increase as the software gets older because it becomes less useful and requires more updates and enhancements to maintain its functionality.
Why is software maintenance expensive
Software maintenance cost is derived from the changes made to software after it has been delivered to the end user. Software does not “wear out” but it will become less useful as it gets older, plus there WILL always be issues within the software itself. Software maintenance costs will typically form 75% of TCO.

Is maintenance of software expensive
On average, software maintenance services cost around 20-25% of the license cost per year, and the rest depends on multiple factors that we will discuss later. For instance, if you hire dedicated software developers for maintaining software, it will cost around $25 to $120 per hour.

Why is it that software cost more to maintain than to develop
Software Life Cycle Costs
Obviously, a more complex software will require more enhancements and other maintenance activities, so the costs go up. According to different industry surveys, maintenance costs as a percentage of build costs vary from 40% to over 90%.

Why is software maintenance difficult
Codes are rarely traceable to the requirements and design specifications. It makes it very difficult for a programmer to detect and correct a critical defect affecting customer operations. Like a detective, the programmer pores over the program looking for clues.
What are the key issues in software maintenance
The key software maintenance issues are managerial and technical. Management issues include alignment with customer priorities, staffing, assigning responsibilities, and estimating costs. Technical issues include: limited understanding, impact analysis, testing, and maintainability measurement.

Which is the most expensive software maintenance
The high maintenance cost of Oracle software is one of the highest across the industry.
Why software maintenance is difficult compared to hardware maintenance
Complexity: Going for software maintenance without a clear roadmap can become complex as it consumes time. This becomes quite difficult to maintain and manage all the different components. Fatigue: Due to the vast number of software product changes, managing them for organizations becomes less effective.
Do software companies have high fixed costs
Software companies have high fixed costs and low marginal costs. This means that if a software…
What are the major causes of software maintenance problems
Causes of Software Maintenance ProblemsLack of Traceability.

What are the 4 types of software maintenance
What are the 4 types of software maintenanceCorrective Software Maintenance. Corrective software maintenance is the typical, classic form of maintenance (for software and anything else for that matter).Preventative Software Maintenance.Perfective Software Maintenance.Adaptive Software Maintenance.
Which type of maintenance is most expensive why
This is an interesting question and generally speaking unplanned corrective maintenance i.e. Emergency Maintenance is the most expensive to conduct. This is because this type of maintenance does not go through the full maintenance planning & scheduling process because it's so urgent and it's simply planned on the fly.
Why software maintenance is a challenge
One of the major key issues is corrective changes because it is hard to find the correct place to do the changes. It can be difficult to recognize the code base. If the preliminary design is reduced a minute change might insist architecture changes that take a lot of time.
