Is there a plan that can be implemented that will allow for the continued development of legacy systems?
If both the software and the hardware of a system continue to have difficulties, at what point should the system as a whole be replaced?
Step by step
Solved in 3 steps
- Is there going to be a significant need for the development of older systems down the road? At what point should a system be totally replaced if it keeps having problems with its software and hardware?To what extent do you have say over how old systems evolve?When will it be more affordable to replace the system as a complete rather than continually updating the software?What options do you have for the evolution of current systems?Is it ever more economical to replace a whole system than it is to update the software on it?
- As software system models are being developed, what considerations should be taken into account?How can the principles of resilience engineering be applied to the design and development of computer systems in order to enhance their ability to adapt to unforeseen events and maintain system functionality?a) With respect to Lehman's laws of software evolution, state the two most fundamental laws and explain their implication for software lifecycle management. b) When you are assessing a legacy system, you have to look at it from a business perspective and a technical perspective. From a business perspective, you have to decide whether the business really needs the system. From a technical perspective, you have to assess the quality of the system and its related support software and hardware. You then use a combination of the business value and the system quality to take one of the following informed decisions: scrap the system, re- engineer the system, replace the system, continue the system's maintenance. Your task is to assess legacy systems in your organization and decide what would be the most appropriate strategy for maintaining these systems. i, Discuss possible factors you would use when assessing the technical quality of the legacy system. ii. Assume that you assessed four…
