The major underlying assumption is that legacy systems are holding up businesses. There is numerous business potential together with the operational value that is tied to legacy systems. The cost of transition to modern or updated systems is not just in monetary terms but also in time (Connolly, & Begg, 2010). There are mainly three ways of combating legacy systems; continue, upgrade or replace. The value proposition of each of the choices is the daunting task for most organizations. Can they take up the cost and effort of replacing a system? How long can they use the current system? Is an upgrade helpful and what are the changes that will come with it? The fact that business is perpetually changing and adapting to new requirements every …show more content…

In the modern business environment, the outlook or perception of many businesses with how they view SOA has greatly changed over time. SOAs are primarily geared towards the use of services. The investment at the onset by the business necessitates a high level of adoption which will prove worthwhile in both the short and long run. SOAs are primarily used for integrating and developing applications for enterprises (Rosen, 2008). Small functions are normally executed by the services such as validating customers providing analytical services and much more.
Challenges in SOA adoption can be classified and put into three categories. These three categories are People, Process, and Technology. When adopting SOA, a buy-in awareness should be there for all at an organization irrespective of hierarchy. It will be unrealistic to expect to reap benefits in the short term. Real benefits will be seen both in the middle and long-term. Individual teams and or departments should have substantial knowledge and commitment for the SOA project to be successful. The reason for this is that they are the same individuals who will be required to develop applications attached to the SOA
Information systems have gone through many changes. Experts currently refer to the current era as the “Customer-Focused Era” of modern computing (Petter & Mclean, 2012).
I would also explain if they are still using a legacy system, which is defined by Barn McDavitt, author of Migration of Legacy Systems, “ A computer system or application program built on what has since become obsolete technology, but continues to be used due to the cost of replacing or redesigning is not feasible.”(Web)
Various benefits will be realized through the implementation of the SOA in the organization (Ross, Curran, and Chapman). First, on accurate implantation, SOA does not need use of new codes. Previously used codes can be reassembled and reused, saving time and other resources in the IT department. This would allow the department a chance to use familiar codes rather than design, test, and implement new ones that may take more time and require a new learning process. Moreover, SOA comes with the benefits of cost saving and increase in business agility. Implementation of SOA will also bring together all the IT workers to work close with relevant partners and other departments on organizational redesign strategies that will ensure an increase in the level of functionality of the departments. Eventually, there will be a suitable coordination between the IT department and other units available at the FBI. Reuse of the existing codes will promote quick adjustment of the workers to the new system. Minimal training will be required and hence, much time will be saved during the implantation
In an article written by Pam Baker named "Six Tips for Stretching IT Budgets in 2009", the writer recommended six tips to get the most value of technology offerings without sacrificing innovations. However, these tips still need some assessment. This paper assesses both positive and negative impacts that those tips have. Of course, the impact is on both operations and strategic investment spending. It will be concise and to the point.
Objective – This just shows if the philosophy for the methodology stated is matched with the objectives, Also to upgrade a computerised information system. Discover whether there is any need for a new information system and also define the limitation of the area interest.
What is the business rationale for making the technology investment? This is one of the most important questions to ask. Almost all companies depend on some technology solution to deliver goods and services. Investing in new technologies for the sake of having the latest up-to-date systems, just does not seem to cut it in the minds of most industry executives, nor does trying to rationalize a major technology investment solely on the basis of reducing ongoing maintenance costs of the old systems. Information technology usually does not have a direct impact on the bottom line. “IT is applied to business processes, and it is those business processes that increase revenue or reduce expenses” [Berman,Knight]. This implies
The Service Oriented Architecture (SOA) uses open standards that should reduce long-term costs, allow more flexibility and make projects manageable across the organization. SOA provides greater business flexibility through its use of web based applications. It will enhance IT services while reducing the cost in hardware and software found in proprietary systems.
The services of a consultant are being engaged to work with the teams at the different levels across the organization to improve and develop the system with all components linked together. They envisage that this system should have standard operating procedures (SOP) – expectations, information requirements, methodology, data collection tools, data analysis procedures and techniques, data quality assurance, reporting channels, dissemination processes and a central repository. The system will have descriptions and documentation of how the various components are supposed to
Many businesses may decide to integrate Service Oriented Architecture with legacy systems to standardize systems across the organization. An organization’s reliance on legacy systems may limit their ability to adopt SOA on a large scale. There are ways of mitigating the transition legacy systems to service orientation.
This article from Business Wire covers broadly the role of shares services in an organization before delving into granular detail that will prove immensely helpful when developing a shared services structure housed in a central location. Business Wire categorizes different types of shared services along with four different organizational models and IT implementation to support the shared services structure. Designing the deployment of a shared services system within an existing organization does require significant IT resources and Business Wire’s work could prove instrumental in mapping out that plan wisely.
The most prevalent factor in the failure of new IT system in general and CRM systems, which customer service is based on, is lack of adoption by the employees that need these systems to do their jobs (Harison, Boonstra, 2009)
Meta description: Companies can hold on to their legacy applications by partnering with a company that provides compatible cloud services and promotes related expertise.
Cloud Computing and Web Services have become well known services that companies have been using. Web services provide the ways that organizations can use applications to communicate with each other across the internet. Cloud computing provides various types of service, such as software as a service, where a provider gives the company software that they can use for their business functions. While this may seem that both types of services are different from each other, they do share similarities that companies should take notice. Service oriented architecture has also started to become a useful feature that helps with integration in companies. One problem is that some companies have difficulty in implementing service oriented architecture, but cloud computing has started to become an option that has caused an impact in service oriented architecture and integration.
The technology of software as a service has been around for a long time and has been used in some form ever since its development. Consequently, the applications associated with software as a service can take many forms and assist users in accomplishing many tasks. The huge thing in today’s market is the ability of running software over the internet and then being able to access the software via an internet browser, from anywhere the user may be. This ability, while not really new, is more common now and used by more and more businesses and individuals as an everyday tool.The convenience factor of this type of service has both positive and negative connotations but due to its wide usage and growing popularity it is very possible that software as a service is going to truly control the information management systems for several years to come. This paper will discuss the use of software as a service (SaaS)and why this type of service is growing more and more popular today, and why it will dominate the information management for some more years.
