Change is ultimately personal and managers must take the time to assess ourselves, our assumptions, and the barriers to promote personal readiness to change. Senior leaders, in particular, are at the forefront of culture and thus enabling change-readiness through role-modeling. Our first responsibility is to inventory our own feelings. If we are resentful, resistant, or apathetic towards the change our teammates will not support it. It is also important to assess our assumptions.
There are assumptions that we often make, such as having a clear definition, a known solution, a clear path, that it is top-down, and that our focus is on systems Kennedy, Lastly, take inventory of change readiness factors Larson, Our assessment data is meant to guide our readiness strategy. The following change readiness strategies represent organizational ways to boost readiness, but since readiness is personal, most deal directly with individuals.
Each tactic should be implemented synergistically in light of our change assessments. Our greatest opportunity is to align our team with the organization through organizational communication and individualized coaching. This message must include why we are changing, the benefits of change, the vision, available support for change, and how stakeholders are expected to participate i.
To capture these necessary elements and to make sure we reach all of our stakeholders in the right way at the right time, it is imperative to map our stakeholders, determine all communication channels, and calculate the best timing. Rodriguez et al.
Similarly, spend some time communicating with the team so that they can participate in the new vision. Perhaps the most profound means of change adoption is through individualized coaching. The team or the organization will not be ready for change if the individual members themselves are not ready. Therefore, co-construct a personal path to change adoption through one-on-one coaching conversations.
In the second part of this article we will explore each of these coaching areas of focus in more detail. Centola, D. The truth about behavioral change. CRC Press. Prosci n.

Facebook Twitter Linkedin. A small update might result in multiple conflicts across the system. Thus, any change or update to the legacy system requires time and effort, neither of which come cheap. Additionally, legacy systems usually have vast amounts of documentation as well as a number of undocumented features.
So, there is always a certain risk involved when interfering with the source code. Just like software itself, the underlying infrastructure becomes harder and more expensive to maintain as it ages. Legacy systems often require a specific technical environment, including hardware. Thus, the infrastructure maintenance spending remains high, as compared to modern cloud-based solutions.
Legacy data represents another significant infrastructure issue. Being scattered across several databases and storage resources, it is hard to reorganize for increased storage space optimization. Gathering and systematizing legacy data manually to further transfer it to a new database is a time- and cost-intensive task. Staff training. Depending on obsolete technologies, the legacy system support and maintenance requires a specific set of skills and expertise. While the developers who have built the software might retire or switch to other technologies, it becomes increasingly harder to find and retain the right talent.
Dedicated staff training might be an even bigger source of expense. Modern software platforms often rely on third-party APIs to access a few capabilities, such as geolocation, user authentication, data sharing, and transactions. For example, Uber relies on the data provided through the Google Maps API for its core functionality — an ability to find and track cars nearby.
Indeed, why reinvent the wheel, when you can use the existing, tried and true solution at a fraction of the cost? Modern technologies are integration-ready by default. API vendors typically provide support for most of the programming languages and frameworks out of the box. Yet, obsolete or rare technologies typically lack the compatibility. Connecting a legacy software to a third-party tool or service often requires a significant amount of custom code. Another aspect of legacy systems that comes at a high cost is compliance.
This is especially true for heavily-regulated sectors, such as politics or law. Meanwhile, the implementation of pseudonymization strongly encouraged by the GDPR is much harder to achieve in legacy IT environments. According to the State of Cyber Resilience , legacy infrastructure is one of the top threats to cyber security. Indeed, legacy systems are usually less resistant to cyber attacks, harmful programs, and malware, which is only logical. If the software solution had been around for years, the attackers most likely had enough time to get familiar with the code and find its vulnerabilities.
Another reason for this is that outdated software might no longer be supported by the vendor. This means that no patches are provided and no one keeps the system compliant with the latest security requirements. Even if your system is custom-built and you have the resources to maintain it, adding more patches means additional investment in security. In the worst case, this might resemble a leaky bucket, where you get a new breach as soon as the previous one is fixed.
By investing in legacy software support and maintenance, you leave less room for innovations. Instead of adopting new technologies and business models, you are stuck with your old software, letting new opportunities in your industry go unnoticed. This leaves your competitors more openings to outperform you and take over your market share. Currently, mobile banking solutions are at the epicenter of customer experience resulting in higher revenue for banks. In this case, the cost of a missed opportunity equals the revenue your competitor will get from newly acquired customers.
Source: Deloitte. Such overhead is another significant element that adds to the cost of missed opportunity. While mobile banking providers save more on efficient and low-cost ways to process transactions, you might still be using outdated POS terminals and manual assistance to do the same job. Talking about business opportunities, timing proves to be crucial. How fast can you respond to the market challenges?
Will it take weeks to adopt new technologies and solutions? Or rather several months? The truth is, in most cases, businesses bound to legacy systems lack organizational agility to adapt to the upcoming challenges. Meanwhile, IT modernization is grounded on agile methodologies which can speed up the provision of IT services by 30 to 50 percent. Although moving from cumbersome legacy IT to agile and digitally enabled IT can be complex and challenging, it is necessary to meet modern IT demands.
Partially due to their inability to be updated and modified, legacy systems can hold back innovation, resulting in significant losses. Moreover, outdated software is less efficient, which has a negative impact on the employee productivity. Machine-reengineering, the business processes automation with the help of machine learning , is a great example of how innovation can optimize business performance. At the same time, some saw a tenfold improvement in workforce effectiveness or value creation. For example, the resource lists a number of successful cases of processes reengineering.
Namely, a financial services provider implemented a biometrics solution based on voice recognition. This resulted in 50 percent more efficient call routing, the improvement achieved largely due to the use of advanced technology. Despite the problems and risks related to the outdated software, a majority of the companies are still lacking legacy-modernization initiatives. Most of them would only consider reengineering the current solution in case of an emergency, such as a complete system outage.
To bridge the gap between the current offerings and customer expectations, companies need to rethink their business models, making them digital-ready. Yet, the legacy software is only one aspect of the problem. Sometimes, a far bigger issue is the mindset that comes with it. That is why proving a business case for software modernization is the first challenge to be faced by the initiating party. So, why modernize legacy systems?
1. What is a legacy system?
The following benefits prove that legacy-system modernization is a vital part of the overall business digitization. Two major arguments are typically used when talking about a software modernization initiative. Those are the time and cost involved. Indeed, a solution that took a team of developers years to implement cannot be re-created in a week, even if you hire twice as many developers to handle the task. Thus, in some cases software reengineering cost might exceed the initial investments. Besides the challenges, there are multiple risks to avoid.
Some of them have been described by a group of Carnegie Mellon University researchers back in Therefore, successful software reengineering requires a solid modernization strategy and great attention to detail. In this regard, we can share some of the best practices and approaches we have developed at AltexSoft. There are more aspects to assess when identifying the legacy. That is why you need to assess all systems in place to uncover the current and potential issues it can bring up in the near future.
The assessment should be systematic and detailed: Study all aspects of your technology, from code and architecture to visual look and feel, taking into account your future business plans for product growth. Select the modernization approach that would be the fastest to deliver value. Based on the assessment conducted at the first phase, choose the modernization approach that best fits your needs and will help you deliver results fast.
Aside from the modernization approaches, consider existing products you can use instead. There is no need to reinvent the wheel if there is an SaaS solution available at a fraction of cost. Yet, if your system solves rather specific tasks or you want to be able to build more features on top of it, custom product development services might be right for you.
In this case, adopting agile software development practices can help you speed up the process and deliver value fast. Legacy systems often fail to perform as needed due to their overly complex structure. When modernizing your system, less is more in terms of both architecture and functionality. Start by implementing only the most important features. Consider a microservices architecture approach to make your product scalable. Additionally, make sure the newly released application will work well with the rest of the tools used in your business by default.
If you plan to change any of the tools soon, consider several possible options and keep their requirements in mind when building your application.
Choose the technology stack to deliver optimal performance and user experience. When reengineering your system, make sure you use a solid and future-ready technology stack. The choice of technologies should completely depend on the product specifics. Consult with your internal IT staff or address a professional tech consultancy. The right tech stack contributes to building a performant, reliable and efficient product.
Adopt a solid quality assurance and testing process to deliver the best results. To avoid the same mistakes that made you reengineer your current solution, introduce or adopt best practices used by other companies a set of coding standards and internal processes. Orderly documented and clean code make your software easy to understand, extend and maintain in the future.
Even if you have a brand-new system running like a clockwork, you will still need your legacy software, just in case. Document and archive your solutions so you can easily access and refer to them when needed. Therefore, you need to support your legacy system for some time and plan for retiring your legacy system only when your new product is up and running. Working with the old systems for years, your employees might need some time and guidance to master the new software.
So be ready to invest in staff training for better performance and efficiency. Additionally, plan for regular system updates. If you fail to keep your product up to date, you will soon face another modernization challenge. Often dealing with legacy systems, we at AltexSoft have developed our own approach to choosing an appropriate way to modernize business-critical software. Namely, we take several steps first to assess the existing solution. The first step in our plan is to identify and analyze the technology stack of the existing product.
Thus, we know if the programming language or frameworks used are still relevant and supported by the vendors. If the product relies completely on outdated technologies, the chances are we would need to completely rewrite it in the process of modernization. In case the tech stack or some parts of it is still relevant, it is necessary to conduct an architecture audit.
This will help you define the system elements which are functioning well and focus on the ones that need modernization. Legacy software usually has an excessive codebase, requiring regular reviews and refactoring. The same principle applies to the UI and UX design. Performance testing aims at uncovering further potential issues with the legacy systems. Poor performance or major flaws can serve as a reason for a complete system reengineering as well as selective improvements.
While considering the current business needs and requirements articulated by the client, we also focus on opportunities for the future growth. Thus, we help you make an informed decision by providing a well-grounded and unbiased opinion on the software modernization options. A well-chosen strategy is an efficient pattern for managing legacy system modernization process. Here are the most popular legacy modernization strategies to consider while planning your technology transformation.
Architecture-Driven Modernization ADM is a coordinated strategy of understanding and advancing existing software assets like its functionality, components, or requirements. The main advantage of ADM is that it approaches modernization from an analysis- and design-based perspective, rather than source-to-source migrations. The main use of architecture-driven modernization comes in the forms of platform and language independency and interoperability. ADM will enable projects with aging software to become more agile. SABA is a high-level framework for planning organizational and technical issues during legacy system evolution and migration.
The framework tackles various legacy system problems while also providing a means to analyze the future implications of software choices. Reverse Engineering Model is a strategy where the legacy applications are gradually migrated to the new environment, but legacy data migration is the last phase of the migration process. To access legacy data, the applications in the new environment use a Reverse Gateway.
Reverse Engineering Model is a good choice for high-cost, long projects that may be undermined by the technology pace. DevOps Contribution allows for speeding up the legacy modernization processes by swiftly deploying new software releases with a low degree of bug or errors while still complying with the target operational IT environment. The system evolves influenced by different development methods — from adding a line of code to complete reimplementation. There are two methods for dealing with the legacy problem that involve major structural changes: revolutionary big-bang and evolutionary band-aid.
Yet, both have benefits as well as drawbacks. The revolutionary method revolves around developing and carrying out a legacy system replacement strategy. Its implementation requires shutting down the old system and building a new one from scratch. The approach might be considered extreme, but sometimes it is better to retire the system completely to avoid some serious damage, such as security breaches, lost data, system downtime.brouwerassurantien.com/cache/monitor/application-surveillance-domicile.php

Or it can be applied in a case when the original product cannot solve the existing business problems anymore, so it makes no sense to reengineer or port it to the new technologies. The evolutionary method presupposes a systematic, step-by-step software modernization process.
It is usually less painful: It does not disrupt the major business processes and implies significantly lower risks for the company. Yet, it often turns into a band-aid method, where you focus on solving the problems instead of removing the factors that cause them.

We need to keep up with that and the business use cases and requirements that may emerge. It is no surprise that many companies stick to modernizing their platforms rather than replacing them. However, synchronizing the operations of new digital and legacy IT teams poses a number of challenges:. Nevertheless, there are many examples of successfully integrated mainframe systems.
Liverpool Victoria is one of them. By separating the mainframe processes from the front end, the company introduced more user-friendly pages and made it easier to add features in the future. Both revolutionary and evolutionary methods serve as a basis for the approaches to legacy modernization that will be described further. According to Gartner , continuous modernization of legacy systems will require companies spend three times more than they are planning to invest till the end of
