What is the most expensive stage of SDLC?
Solution(By Examveda Team) After Maintenance, Implementation is the most expensive task.
During which phase is it most expensive to fix an error in SDLC?
The Systems Sciences Institute at IBM has reported that the cost to fix a bug found during the implementation stage is approximately six times more expensive than one identified during design; the cost to fix an error found after product release is then four to five times as much as one uncovered during design, and up …
Which phase has the highest cost of bug in the software?
The cost of fixing a bug or defect is lower if you catch it in the design phase, but higher in later phases of the software development life cycle (SDLC).
Which phase in the SDLC is the most important?
requirement collection and analysis stage
All SDLC stages should be valued equally. However, many software development experts suggest that the requirement collection and analysis stage is the most important aspect of SDLC. This is when the project team begins to understand what the stakeholders expect from the project.
Why the system maintenance phase is often the most expensive phase of the software development life cycle?
The primary reason that the maintenance phase last longest is the life of the software. Most software programs remain in operation until they become obsolete due to changes in a user’s needs or until the cost of maintaining the software becomes prohibitive to future use of the software.
Why cost of software maintenance is high?
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.
What type of change in a system is the most costly?
But often physical rebuilding is the slowest and most expensive kind of change to make in a system.
In which of the below phase is the defect comparatively less costly?
Therefore, requirement gathering is the correct answer.
What is bug cost?
The cost of a bug goes up based on how far down the SDLC (Software Development Life Cycle) the bug is found. Then there’s the domino effect to think about. The software development approach often need to change to accommodate the code fix, which can in turn bump back other code changes.
Which phase in the SDLC is the most important quizlet?
The planning phase in SDLC is the most important phase because during this phase the project team identifies the business value of the system, conducts a feasibility analysis, and plans the project.
Why do you think that the maintenance of software is expensive?
As technology advances, it becomes costly to maintain old software. Most maintenance engineers are newbie and use trial and error method to rectify problem. Often, changes made can easily hurt the original structure of the software, making it hard for any subsequent changes.
Is maintenance cost will be higher than development cost?
Explanation: Maintenance costs are greater than the development cost. It is affected by both technical and non technical factors.
What is the cost of maintenance?
Maintenance costs are the one-time or recurring costs a company incurs related to maintaining company facilities, property, vehicles or equipment. Some companies incur these costs for general or preventative maintenance that help keep their assets in proper working order.
What is the most expensive energy source?
‘Nuclear power is now the most expensive form of generation, except for gas peaking plants’ The latest edition of the World Nuclear Industry Status Report indicates the stagnation of the sector continues.
What is the cost of change?
The cost of each change increases because we have more time, money and energy invested. Sometimes the cost is not actual, but inferred — because we don’t “want” to make the change. We’ve put a lot of effort into something and change means discarding at least some of what we’ve done.
In which phase the defect is less costly MCQ with answer?
What is defect cost?
The cost of defects can be measured by the impact of the defects and when we find them. Earlier the defect is found lesser is the cost of defect. For example if error is found in the requirement specifications during requirements gathering and analysis, then it is somewhat cheap to fix it.
Which phases of the SDLC is the most important and why?
Which phase in the systems development life cycle is the most important? The planning phase is the most important because it is the first step. Without having a clear organized plan the rest of the phases will fail. A plan is the foundation for how the rest of the project will go.
What are the most important phases of SDLC life cycle?
Here, are some most important phases of SDLC life cycle: The waterfall is a widely accepted SDLC model. In this approach, the whole process of the software development is divided into various phases. In this SDLC model, the outcome of one phase acts as the input for the next phase.
What is the SDLC model?
SDLC provides a well-structured flow of phases that help an organization to quickly produce high-quality software which is well-tested and ready for production use. The SDLC involves six phases as explained in the introduction. Popular SDLC models include the waterfall model, spiral model, and Agile model.
What is the second step of SDLC process?
The second step of SDLC is gathering maximum information from the client requirements for the product. Discuss each detail and specification of the product with the customer. The development team will then analyze the requirements keeping the design and code of the software in mind.
What is the fourth stage of SDLC?
In this fourth stage of SDLC, the tasks are divided into modules or units and assigned to various developers. The developers will then start building the entire system by writing code using the programming languages they chose. This stage is considered to be one of the longest in SDLC.
