  • Industry: IT Services
  • Size: ~1500 employees
  • Use cases: Profitability Tracking and Forecasting, Resource Planning, Resource Management, Reporting

Overview

When Billennium first decided to look for a comprehensive tool, it was already a large business. Still, with that size came complicated processes handled in oversimplified tools – and they were about to reach their limits. 

By the time the company reached 1500 employees, it had become apparent that the tools offering basic resource management and time tracking only covered a fraction of the necessary processes. Without finances, forecasts, or skill management, the managers were limited from expanding their skills, optimizing their projects, and generating additional profits for the company. 

As long as the two tools weren’t connected, we had to live with unintegrated data. We were looking to strengthen our financial perspective, which we only obtained by implementing BigTime.

Still, Billennium’s Directors, Łukasz Sawicki vel Sawczenko, Head of Performance Management, and Piotr Kawęcki, Head of Business Delivery, refused to bulge and adapt their processes to the unsustainable tool. Instead, they decided to look for solutions tailored to the needs of IT services companies, using the experiences of dozens of similar companies enclosed in the tool, and tailor their processes accordingly. 

Having found BigTime, they didn’t need to look any further. Instead, they decided to use their skills to help their organization embrace BigTime’s features in a record-breaking time – all with over 1500 people on board. 

Using BigTime’s implementation process, Billennium trained all its employees and reshaped its processes in three months, achieving complete data transparency. By doing so, it unlocked advanced calculations, utilization management, financial forecasts, and more, giving its managers all the tools they needed to boost profitability and productivity in a competitive environment, along with the added value of expanded planning and control horizons. 

What Did Billennium Need to Bridge The Gaps? 

With only basic resource management and time tracking, Billennium’s data could not be used to drive any improvement or optimization. For a company of this size, this posed a significant risk. 

With no overview of utilization, future allocations, and costs calculated in Excel, Billennium risked facing an excessive employee bench and declining productivity statistics, which could ultimately impact the company’s overall performance.

At one point, we observed a swift expansion of the employee bench, which reached over 100 people within weeks. This showed us that there was an opportunity to better anticipate upcoming needs. It was a signal for us to find a tool for sharing the data with everyone in charge—both business and teams responsible for allocations.

Due to a limited tool scope, Billennium could only analyze information on project execution and past budgets—provided they were first calculated in Excel spreadsheets. However, once the data was available, the processes could not be optimized or impacted. In short, existing tools limited Billennium’s potential, highlighting the need for solutions supporting future growth and operational improvements.

Our former tools didn’t provide an answer to the most important question: What will the financial outcome of the next period be, and how can we still manage and improve it? We were overly focused on analyzing the past rather than monitoring and improving future outcomes. This lack of tools to influence future results led to many unpleasant surprises, which confirmed that we had been focused on the past—something we could no longer modify.

The Challenge: 1 Implementation, 1500 People – and Just 3 Months

The expansion of processes required significant adjustments and broad knowledge. Still, when paired with over 1500 employees, the implementation was an even greater challenge. 

Fortunately, when a scalable, battle-tested process provided by BigTime met with Billennium’s managers’ experience and determination, the implementation became not only possible and smooth but also exceptionally quick. 

It’s been three months since we started to research the topic until the tool was introduced – and this is an implementation time for over 1500 people in three locations, all with complicated billing models.

Preparations

Before the implementation began, Billennium and BigTime took time to prepare plans to guarantee its success. 

First, the responsibilities were divided among two product champions: 

  • Łukasz Sawicki was responsible for managing the data.
  • Piotr Kawęcki, who was responsible for business operation processes.

Based on this division, the conjoined forces of BigTime and Billennium created a list of tasks containing all the activities required for the implementation to begin. Those actions were then monitored in a designated tracker, allowing all parties to oversee and complete the process on time. 

Live Tests

With all the necessary data and processes rearranged, Billennium was ready for the first test of BigTime’s capabilities. Its aim was simple: to determine whether or not the two environments can match and integrate properly. In Piotr’s eyes, there was only one way to do that: to use the experience of similar companies in the tool to reshape and strengthen Billennium’s processes. 

The tool contains the experience of both the customers and the provider. If my company differs from that essence, are its processes truly up to the industry standards?
Piotr Kawęcki Head of Business Delivery, Billennium

This pioneering decision significantly simplified Billennium’s processes, making them less time-consuming and more accurate than ever before. Simultaneously, the managers’ learning curve was minimized, helping them quickly familiarize themselves with and take over the key processes. Thanks to such an innovative approach, the test was a complete success powered by both teams’ dedication and comprehensive knowledge. 

Go Live

With promising initial test results, Billennium was up for yet another challenge: data transfer—not just for one team but for the entire business of 1500 people and all their projects. 

Both Billennium and BigTime accomplished that goal, too. The former provided advanced analytics, and the latter designed an implementation framework. The data were quickly imported from old documents and tools to the new ecosystem, and soon, the results of the transfer were seen in Billennium’s financial statements. 

Feedback Loop

Like any other highly advanced IT services company, Billennium’s journey did not involve transferring the last megabyte of data. Instead, the company adopted a more proactive and future-proof approach and created an organization-wide feedback loop, helping the business better communicate and address new challenges with BigTime.

As a result of this process, Billennium was able to monitor the changing needs of its departments and, with help from BigTime’s team, expand the capabilities of both the tool and Billennium’s team, facilitating further growth. 

BigTime can scale to fit the needs of smaller and bigger organizations by turning on additional features and allowing the tool to grow with the business. We, too, turned on some of its modules as we progressed – they were yet another step toward our organization’s operational and margin maturity.
Piotr Kawęcki Head of Business Delivery, Billennium

Integrations: Data-Driven Processes Taken One Step Further

As Billennium offered customers dozens of different services with different billing models worldwide, it encountered some unique challenges requiring a more personalized approach – and BigTime provided it once again. 

When operating separately, BigTime would not be as valuable. Its greatest advantage is its ability to connect with other systems through dedicated and accessible API, which helps us avoid creating some remote informational desert islands.
Piotr Kawęcki Head of Business Delivery, Billennium

Taking into account the specific problems of large businesses, BigTime has offered a variety of integrations that could later be used to expand the system with both bespoke solutions and other systems. Billennium utilized this capability to use the tool’s data for its own BI solutions, reflecting its operations’ characteristics. As a result, it gained a whole new overview of various projects, locations, statistics, and more, further boosting its operational advancement. 

Results

With a complete overview of people, plans, and finances, Billennium finally had all the data it needed to improve its management processes on every level. 

When combined with adjustable roles in the system, such an efficient information flow contributed to managers’ decisions. With the right data, they effectively became the CEOs of their projects, actively improving their performance throughout their duration and generating additional income. 

I don’t have to await the end of the billing period anxiously. Our forecasts barely differed from reality, giving me peace of mind in my work.
Piotr Kawęcki Head of Business Delivery, Billennium

The changes on the project level were then paired up with company-wide improvements. Active utilization management, instant skill matching, and real-time analysis of every project and allocation helped Billennium improve its key performance indicators, boost profitability, and raise its profit margin.

Profit margin and income: these are my goals and the goals of my organization. With BigTime, I could achieve them, as it allowed me to identify profitable processes and focus on them to boost margin.
Piotr Kawęcki Head of Business Delivery, Billennium

Thanks to BigTime, Billennium gets to enjoy benefits such as: 

  • Record-breaking utilization boosted by over 14%. Billennium improved its planning, making the most of its employees’ time and generating profits from every working hour. It also reduced employee benches and cut costs, further contributing to better financial performance.
  • Improved financial performance. According to both Łukasz and Piotr, the changes in essential processes and project management resulted in tangible benefits, including optimized operations and, consequently, 
  • Optimized KPIs in the projects. Having the data to act on, project managers took control of their operations and maximized their performance, providing the company with additional income and themselves – with attractive bonuses.
