1. What are the fundamental elements of a legacy system? Scrap the system complexity this choice ought to be picked when the system is not making a compelling commitment to business forms. This regularly happens when business procedures have changed subsequent to the system was introduced what 's more, are no more dependent on the legacy system. 2. Leave the system unaltered and proceed with customary upkeep This choice ought to be picked when the system is still required yet is genuinely steady and the system clients roll out generally few improvement demands. 3. Reengineer the system to improve its maintainability this choice ought to be picked when the system quality has been debased by change and where another change to the system …show more content…
The application system must be modified to adapt it to cope with these environmental changes. 3. Functionality addition: This type of maintenance is necessary when the system requirements change in response to organizational or business change. The scale of the changes required to the software is often much greater than for the other types of maintenance. 9.3 software maintenance 3. What process metrics might be used to assess maintainability? Examples of process metrics that can be used for assessing maintainability are as follows: 1. Number of requests for corrective maintenance: An increase in the number of bug and failure reports may indicate that more errors are being introduced into the program than are being repaired during the maintenance process. This may indicate a decline in maintainability. 2. Average time required for impact analysis: This reflects the number of program components that are affected by the change request. If this time increases, it implies more and more components are affected and maintainability is decreasing. 3. Average time taken to implement a change request: This is not the same as the time for impact analysis although it may correlate with it. This is the amount of time that you need to modify the system and its documentation, after you have assessed which components are affected. An increase in the time needed
5. Why are software updates so important? Be sure to include security fixes, bugs, adaptation to new hardware availability and other plugin options.
As for implementing these changes can cause some problems and issues, moreover this is time consuming process.
The process of evaluation, development, and validation will be a constant. Due diligence will be one of the most important tools in software management and maintenance.
Considerations will be implementing upgrading the entire network the new system will rely upon, in its current state it will not sufficiently support the projected needs of the new system
4. What problems under the old system are solved or mitigated by the new system?
Another way of successfully gathering information is by building a prototype or model of the system, so that users can test or get an idea of what the finished product will be like. With this they can determine issues, problems, or inconsistency with the system. Another important part of gathering information is organizing it so that it can be understood and put to proper use. I propose categorizing the requirements into functional requirements, operational requirements, technical requirements, and transitional requirements. The functional requirements define how the user thinks the system is functioning overall, the operational requirements define what background processes need to be executed in order for the system to work optimally over a period of time, the technical requirements define what technical issues that must be addressed in order to successfully implement the system, and the transitional requirements define the processes or steps needed to implement the system smoothly and successfully. ("Mind Tools", 2012).
-In the case of algorithms that tend to be changed, the unit tests for that part of the code would require to be changed too. So this means to spend time again to fix the tests.
The following data consists of the actual time used and potential (the best time possible for this review process) to complete each step in the review process. The actual times are based on the review of 30 projects. The potential times are subjective engineering judgment estimates.
Severity of Impact – The severity of the impact is considered medium. If user application performance is negatively affected, the users will not be able to meet their daily expected workload. In other words, users will not be able to complete their assigned tasks timely.
Using the scenario information supplied, the candidate will undertake a cost-benefit analysis for high-priority change requirements, undertake a risk analysis, identify barriers, and develop
c. What do these changes say about the sensitivity of OPM and its applicability to IT projects?
This is an issue for current processes because there are often incomplete system requirements at the start of development and because requirements may change and the process is not set up to adapt to late-breaking changes.
In field of project management, there are a plethora of mechanisms under perpetual reevaluation. One specific segmentation of project management under such scrutiny pertains to cost duration, which is the time and monetary costs of completing individual tasks within the project’s critical path (IBM Knowledge Center, 2016). The process of monitoring and evaluating the time and financial impacts of each task is referred to as cost duration analysis (IBM Knowledge Center, 2016). A chief concern of cost duration analysis is identifying tasks within the project’s critical path which can reduce project duration (PMI, 2013). A common approach to reducing a project’s duration is task “crashing” (PMI, p.181). According to The Project Management Institute (2013) crashing refers to the process of methodical determining the financial value of increasing a critical path task’s resources in order to decrease project duration (p.181).
This “inspect-and-adapt” technique reduces the development cost and release time for the project is kept
Business must endlessly update their systems to keep up with the changes that occurs with their business process. Business processes are continually trying to find many ways to accomplish new and shifting goals for the business. New or shifting goals, such as changing the responsible for a current business process, or combining more than one responsible into one can be difficult and needs a clear understanding of multi-tiered systems and the business processes itself. The absence of connection among requirement and employment can lead to problems in recognizing the suitable program which must be changed to further increase the worthiness of a system in response to the new goals. Unfortunately, these changes can lead to errors and can make take longer than expected.
