How To Improve The Outdated Processes Of Your Legacy Application
The term 'Legacy Application,' as it applies to an application or the software library it contains, refers to the application that a company developed before it acquired another application. In most cases, this second application is often a subset of the first. When an organization acquires applications, it usually involves a significant amount of financial and time investment. In many cases, these acquisitions result in a company investing in the development of new applications. However, there are instances where legacy applications are re-developed to support future business models.
Organizations can opt to re-develop a legacy application through the purchase and licensing of a software product with improved functionality. Organizations often purchase application products that include components associated with a specific programming language, database, and web development technologies. These components are necessary to develop an application. Examples of software available for purchase includes application server technology, application packaging technologies, and web server technologies.
Through application modernization, legacy software can be made to meet the needs of an evolving enterprise. These software components can help to ensure that legacy systems can be updated without requiring drastic modifications to the applications themselves. The increased efficiency gained from these endeavors can lead to substantial cost savings. Some of the additional benefits derived through these programs include simplified reporting, simplified configuration and testing processes, improved usability and reduced maintenance costs.
As organizations continue to evaluate their software needs, they may seek to replace outdated software through acquisition of a Software as a Service (SaaS) application, or develop a customized software solution. These options enable businesses to reduce IT expenditures by substituting expensive licensing models for software that has no direct commercial use. Software development environments and tools are evolving to make developing software easier, faster, and more efficient.
Many companies choose to acquire software development technologies via the private or public sector. There are a variety of approaches to software development, including software engineering, Open Source development, in-house software development, and software consulting services. Acquiring software through acquisitions or purchasing a specific piece of software is often the most economical means of transforming legacy applications. Businesses must evaluate their software budgets in order to determine which types of technologies to make the most sense for their application. Often this will require partnering with a vendor who specializes in the technologies that best suit their business's needs. Software application modernization can also entail utilizing third party technologies, although this practice carries additional risks and costs.
Another method of transforming legacy applications is to develop a custom software solution. Custom software development requires upfront financial investments but produces long-term cost savings. In some cases, these solutions can reduce the development time needed for new technology by as much as 90%. Another way to transform legacy applications is to implement improvements through an organizational change management program (IDSCM). This approach helps organizations to make the best use of their existing software and to reduce the cost associated with implementing new applications. Since many IDCMs require a change in business rules, this approach can sometimes require a long engagement process with key personnel within the organization.
Organizations may also turn to the technology community for assistance in improving the functionality of their legacy application modernization. Technology transfer strategies can help to ease the transition from legacy systems to a more contemporary service platform. These strategies often involve cooperative efforts between the technology community and the business. Some of the common techniques used are migration of legacy data to a new database server, integration of new enterprise-level enterprise applications to the already existing legacy system, and the use of simplified business processes (SBS) to create a more streamlined service environment. Another strategy that has proven effective is the use of technical test automation to reduce the time it takes testers to test new software.
With the right strategic planning, organizations can successfully transition their legacy application systems to a modern business environment. The benefits of this solution can have a dramatic effect on both the operational quality of the business and its profitability. Although these methods do require some upfront investments and a significant amount of time, they are more than worth the effort because they can effectively bring your legacy application up to date with the latest market trends and technologies.
