The problems with legacy HR software: 7 steps to build a business case for a new HR system

Building the business case for HR software requires first looking at why your existing system might be failing you and then what could be achieved by upgrading. In order for your HR strategy and initiatives to deliver actual value for your organisation, it is vital to adopt software that is fit for your organisation’s unique requirements, now and as you grow. Outdated legacy systems can result in inefficiencies and potential for errors the longer they are relied on to do a job they can no longer do.

Many organisations are now facing technical debt caused by rushing to implement a HR solution during the pandemic. Whilst providing a short-term fix, it may not now be scalable or suitable for specific HR needs. We look at the 8 common problems associated with outdated HR tech and the 7 examples of how to build the business case for a new HR system.

What signals should you consider before building a business case for a HR system?

It’s not change for the sake of it, but about businesses being able to recognise the detrimental effects of repetitive problems that suck the life from HR functions’ efficiency and energy levels. Substandard systems may come in different shapes and sizes, and there are several signals and signs that indicate the systems may have hit their limit.

1. Are your systems disconnected? 

Juggling separate systems for recruitment, onboarding, payroll, benefits, time tracking, and performance reviews creates numerous problems. Non-communicating systems force manual data re-entry, increase errors, create data silos, and prevent a unified view of workforce information. This patchwork approach signals the need for an integrated solution like PeopleXD Evo

2. Are you wasting time on manual tasks? 

When HR teams spend excessive time on repetitive administrative tasks efficiency suffers. These processes are costly, error-prone, and frustrate both HR staff and employees. A system like PeopleXD Evo is designed to automate simple tasks, allowing you to focus on your people.

3. Do you have insufficient data to make strategic decisions? 

Making workforce decisions based on intuition rather than reliable data is risky. When accessing and analysing HR information is cumbersome or produces outdated results, you're missing critical insights that an AI-enabled system like PeopleXD Evo can provide in an instant. 

4. Is it preventing further growth? 

Systems that functioned well for smaller operations often falter under the pressure of growth. As employee numbers increase and operations expand, inadequate systems become slow, create bottlenecks in essential processes, and lack features needed for larger organisations. PeopleXD Evo is designed to scale with you. 

5. Is your workforce too complex for a simple system? 

Organisations with diverse worker types, multiple locations, complex scheduling, or varied benefits packages require sophisticated HR solutions. Basic or outdated systems rarely offer the flexibility to handle these nuances, leading to payroll errors, compliance risks, and administrative challenges. 

If your current HR systems are creating any of the above issues, it’s likely time to consider a HR software business case. Whilst making a change can be daunting, it is far less problematic than the time taken to fix errors or design workaround processes to make your system work the way you need it to.

The benefits of a new HR system

The chances are that if your HR department isn’t functioning at an optimal level, some or all of the flaws mentioned above will strike a chord. They also reveal that it’s not typically people that are the problem, but rather the tools that teams work with and which have an immense impact on their ability to excel at what they do.

In addition, employee engagement, productivity and retention are all closely linked to the ease of which employees are able to find what they need and get on with doing the job they’re paid to do. That’s where upgrading your HR system can make all the difference. There are many more benefits of a modern HR system, for instance, it will:

Achieve ROI

Setting goals or targets for a new system is fundamental to its success. You should be able to then demonstrate using the system, how you’ve achieved these goals.

Save total cost of tech ownership

Upgrading siloed HR systems to an integrated solution can help save on your overall operational expenses (OpEx).

Empower employees with self-service

Self-service software inspires greater autonomy and control among staff, whilst also freeing up time spent on managing holidays, tracking absence and answering frequently asked questions. The time you’ll save through automation can then be reinvested in strategic planning to support things like employee engagement, development and performance.

Handle growth

Your new HR system should be future-proof, meaning it’s scalable and with the ability to grow along with your organisation, reducing your requirement to upgrade again in the next few years. For example, whilst PeopleXD Evo is tailored for medium-to-large businesses, it can be implemented at different stages of growth. It can then consequently scale with you, offering you extra features to turn on, all backed up by AI-powered support and embedded People Analytics. 

Integrate with other systems

Syncing data and functionality from one application to another using an API (Application Program Interface) could tick the integration box for your organisation. But, a fully end-to-end HR system will include broader functionality than simply people management and HR records, allowing for a seamless flow of data across the employee lifecycle, from recruitment, to onboarding, learning and talent and performance management increasing visibility of your people data and improving efficiencies. A joined-up system makes it easier for new data to be shared instantaneously between functions and with less risk of human error.

Be accessible

With a cloud-based HR system, employees can access data anywhere from any device, and it will be updated in real time, increasing levels of engagement and productivity.

Enhance the employee experience

The organisations who hire the most dynamic, skilled workforce are those who demonstrate the best employee experience. The employee experience starts at the recruitment stage, and should continue throughout the time they’re with your organisation. End-to-end HR systems drive employee engagement, saving employees time and reducing frustration.

Attract and retain talent

Enhancing your employee experience with a more intuitive HR system can help with talent attraction and retention and contribute to reducing attrition costs. Attracting and retaining talent are two significant advtanges of becoming an employer of choice. For strategies to become an employer of choice, read our ‘7 Proven Steps to Build an Employer of Choice Culture’ blog.

Streamline your onboarding experience

A slick and informative hiring and onboarding portal will impress your new recruits and set them up for success from day one. This also makes it possible to automate aspects of induction training and ask new joiners to complete initial compliance tasks before their actual start date, so they’re ready to hit the ground running. Once through the door, systems can also help you automate data collection about the onboarding process through onboarding surveys, an example of which you can find in our ‘Onboarding Survey Template’ blog. These can help you improve your onboarding experience. 

Use valuable data insights to inform decisions

HR teams should be able to rely on their HR system to generate the valuable data and reports they need to share insights with key stakeholders and contribute towards key business decisions. AI-enabled HR systems will centralise your people analytics data, making it simpler to cross-reference and visualise substantial datasets, and generate reports within just a few clicks.

How to build a business case for a new HRIS: 7 steps 

When it comes to building the business case for a new HR system, you need to have completed some substantial background research including the problems you have with your current systems and what your new system will need to do.

Technology is developing at a rapid pace and many people are now working in a remote capacity; 92% have reported that their organisation’s approach to where, when and how people work has changed and it is imperative that HR systems are able to keep up with these developments. An outdated or disconnected HR system is no longer viable.

Initially the key considerations when building an HRIS business case in a scaling organisation should be around levels of integration, mobile functionality and automated workflows needed. You will also need tangible statistics and data, available in your current systems, to support your recommendations. If this data isn’t reliable or easily accessible, you have the start of your business case already.

The key to success is to pitch your requirements from an HR perspective as well as from a wider business perspective. To get decision-makers on your side, you need to ‘sell’ the idea to them and make clear not only how you and your department will benefit, but also how perceived hurdles can be overcome and, ultimately, how the solution will help the company to meet its goals going forward. 

Presenting a strategic business case will showcase not only the specific reasons behind a new HR system, it will also highlight the risks of doing nothing, such as issues you have with your current system which could impact the objectives and productivity of your whole organisation.

Take a look at the following seven key steps for building an HR system business case:

1. Involve key stakeholders

It’s important to involve multiple stakeholders to find out what the challenges and requirements are for IT, Data and Finance departments for example, to ensure the business case fits with wider organisational objectives. Sign-off for the new HR system may take a while so sharing your intentions with the decision makers and weaving their initial queries into your plans will help with the final hurdle.

2. Recognise business needs

Reviewing your current system with a critical eye will help recognise what is missing and identify pain points. With a long list of competing priorities, it’s not always easy for decision makers to allocate budget so they need to be convinced just why a new HR system should be implemented. Getting feedback from multiple business functions, setting up tests or focus groups and asking employees for their suggestions is all useful preparation.

3. Gather data on current position

It is vital to collate data on the current position and then continue to build on that picture as it develops. When you are actively monitoring and measuring HR metrics, you can present an evidence-based argument and show progress and performance once you have put changes and tools in place.

4. Prove there is a problem

You already know that there are issues with HR delivery that can only be solved with a robust, fit for purpose HR system. You may be having to work with an out-of-date solution that no longer meets your needs, or worse, a cobbled together set of spreadsheets, databases and paper systems that make it difficult to stay ahead of the game and impossible to produce any meaningful management information. Focus areas to look at include:

  • Inefficient processes and disconnected systems
  • Data compliance
  • Information security
  • Management insight

5. Identify the benefits

The next step is to look at the benefits a new HR system could bring to your organisation as a whole, including the problems it would be able to solve with ease. Whether this is by improving employee engagement, integrating real-time reporting and analytics or drastically reducing admin time, it is important to showcase just why you should be making these changes and the long-term impact they will have. Work with an external consultant or a HR software provider to identify these benefits and how you will measure the ROI of the software when it is implemented.

6. Do your research

The next step is to look at the benefits a new HR system could bring to your organisation as a whole, including the problems it would be able to solve with ease. Whether this is by improving employee engagement, integrating real-time reporting and analytics or drastically reducing admin time, it is important to showcase just why you should be making these changes and the long-term impact they will have. Work with an external consultant or a HR software provider to identify these benefits and how you will measure the ROI of the software when it is implemented.

7. Create and present your plan

The final step for a HR system replacement business case is to bring everything together and propose the next steps with a detailed plan of action. State both short-term and long-term projections and expected return on investment and obviously resource and budget that will be required. This is your chance to showcase just why a new HR system will offer tangible results for your organisation as a whole.

What do other departments need to know?

IT Team

When putting together a HRIS business case, you must consider the needs of the IT team in order to prepare for the objections or hurdles that will need to be overcome and create the best chance of a positive outcome.  

Choosing and implementing an HR system will be another priority to add to what is probably already a long list of IT priorities for the business so it makes sense to think about the issues that might arise in order to smooth the process of moving forwards. In fact, for a larger business, any new software project should involve the CIO, IT Director or equivalent from the start, to help identify and scope out needs and goals and ensure the best results. 

Think about the following questions: 

  • What will the testing and ‘go live’ process be? 
  • What is the implementation process and how long is it likely to take? 
  • Does the proposed software follow best practice? Are you choosing best of breed? 

It’s important that the IT department are kept in the loop on implementation timeline, so they understand how and when they need to be involved in the process. Read our guide on how to implement HR software in six steps to get a full plan on how to implement, and when to get your teams involved.

Finance Team

Similarly, a representative from the Finance team will ideally be involved in a new HR software project from the start, particularly in a full HR transformation project where return on investment will need to be closely identified and measured in order to demonstrate success.  

Financial decision-makers are interested in three core areas:  

  1. What is the cost of doing nothing?
    For example, if you were to keep your existing HR system, along with the challenges that brings, what will the tangible and intangible impact be on the business? Answering this question gives you the opportunity to identify the value of time and resources being invested vs wasted. Assign monetary value to inefficiencies based on an hourly rate and time spent. From here you can easily build a monthly cost picture of continuing to function in the current format. Agencies, software providers and consultants are often able to help with this exercise right from the start.
     
  2. What cost savings could be made?
    Define the time savings and corresponding monetary value with a new, more efficient HR system in place. Think about the key functions that can be automated. Assign costs to one-off tasks such as responding to data access requests or creating a management report for the Board meeting. 
     

  3. What new costs will be incurred?
    Provide a summary of the investment required to support the proposed new system including up-front and ongoing costs.
     

Ensuring that IT and finance departments are a core part of a new project when building an HRIS business case system is essential for a well-rounded, holistic approach. It promotes collaboration, addresses technical and financial concerns, enhances data security, and increases the chances of a successful implementation and engagement. 

What other factors should be considered?

When putting together your business case for HR software, it is also important to include other considerations which may crop up. Below are some factors that may be added into your HRIS business case alongside your main steps.

Anticipating changes to budget

You may be in a position where your budget is uncertain further down the line which could impact the HR software you are able to implement. It is important in this case to look into the scalability of the software, alongside prioritising the most important factors, and looking at multiple different options to find out what flexibility and customisation is available.


Creating a CIP

A continual improvement plan may be required for longer-term planning. You may not be in a position to fully implement every aspect of a new HR system in one go, so preparing for this within your HR business case will help manage expectations of your stakeholders. Consider what can be included at this stage, and then what the plans are within the next 12-24 months. The HR landscape will likely look different so it is important to prepare for this as much as possible.

Flexibility for add on features

Implementing a HR system which is scalable and flexible is imperative for any organisation. Being able to add and remove features as required will help in both budgetary respects and for when an organisation goes through a period of growth. It would be a shame to implement a system which is integrated, seamless and easy to use but restricted in how much it can offer on a longer-term basis. Being aware of the limitations of a HR system will help at the planning stage and when discussing with stakeholders, who will want to understand the long-term benefits.

Your existing resources

If you are a small business (below 100 people), you may not have the in-house resource or budget to facilitate a large-scale HR transformation. In this instance, it may be more appropriate to opt for a simpler ‘out of the box’ solution, like Access PeopleHR. Such solutions provide functionality catered specifically to the needs of smaller businesses and work off an agile plan and pricing structure.

What are the disadvantages of updating legacy HR systems?

When building your HR business case, there will likely be a number of questions or concerns that arise from senior stakeholders that may be more reluctant, whether that’s because of risk, budget or resource. Employees may already be comfortable and familiar with their current HR system’s features and functionality and may not want to go through the time and effort required for any training or onboarding on a new system. However, if a new system is intuitive, then employees should easily be able to pick it up without needing to go through an extensive training process.

A HR system with increased automation and mobile accessibility for example can help drive productivity and employee engagement, saving employees valuable time.

The focus of HR must shift towards building the organisation of the future. Now is the time to plan ahead and stake a claim for the evolution of culture, talent practices, learning and development and employee experience – and integrate the necessary technology to deliver it. Decisions made now will have a far-reaching impact on the ability for organisations to thrive, especially with choosing the right HR software. And whilst some employers may be thinking only in terms of stopgaps and short-term fixes, those that invest in the bigger picture of HR transformation will reap the benefits of attracting and retaining top talent, maximising wellbeing, and developing greater resilience for years ahead, rather than months.
