Procurement transformation at enterprise scale is rarely a technology problem.

The platforms exist. The business case is clear. The process design can be defined. The implementation plan can be managed.

What determines success — or stalls it — is whether the organization can build and sustain the momentum required to move thousands of people from entrenched buying behaviors to new ways of working without disrupting the business continuity leadership depends on.

For one Fortune 500 financial services enterprise, that was the defining challenge in a multi-phase Source-to-Pay transformation using Zycus.

NSP & Company served as the strategic change and transformation partner, working alongside the CPO, his direct reports, the program leadership team, and functional workstreams to help the organization move beyond go-live and build the conditions for sustained procurement adoption.

The Change Momentum Index® was applied at key intervals throughout the program to help leaders see where momentum stood, where adoption risk was emerging, and what leadership action was needed next.

The goal was not simply to launch a platform.

The goal was to help the organization move.

The context: complexity at scale

The client operates across North America, EMEA, and APAC — a market-leading financial services organization with complex regulatory obligations, distributed stakeholders, and a procurement function under significant pressure to modernize.

Leadership had committed to a multi-phase Source-to-Pay transformation with aggressive timelines to deliver the U.S. go-live, updated procurement guidelines, and subsequent international rollouts beginning with Canada.

The transformation required more than system implementation. It required a structural shift in how the organization purchased goods and services, engaged suppliers, routed approvals, coded transactions, and adopted a more disciplined procurement operating model.

The challenge was not the technology.

It was the organizational reality surrounding it.

Thousands of associates had different buying patterns. Approval chains were complex. Readiness varied across functions and regions. Executive assistants played a critical role in daily adoption. Suppliers needed to understand and use a new network. Finance, procurement, technology, and the business needed to stay aligned while the program moved through launch, stabilization, and subsequent deployment planning.

Without a deliberate strategy for building momentum, the risk was not only failure at launch.

The greater risk was stalling in early Acceleration — where progress is visible, but fragile — and never reaching the sustained adoption required for transformation to hold.

The approach: See. Move. Build.

NSP integrated directly with the program leadership team and functional workstreams from the outset.

The work was not treated as a communications and training effort attached to a technology rollout. It was treated as a strategic organizational change program requiring leadership alignment, governance discipline, stakeholder movement, adoption infrastructure, and real-time issue resolution.

The Change Momentum Index® gave the leadership team a practical way to read momentum at key intervals throughout the program. It helped identify where the organization was building traction, where adoption risk was emerging, and where leadership attention was needed to keep the transformation moving.

CMI® also gave the CPO, his direct reports, sponsors, and program leaders a shared language for what was happening beneath the status report.

The question was not only: Are milestones being completed?

The sharper question was: Is the organization building the momentum required for this change to hold?

NSP's work followed its See. Move. Build. approach.

See the momentum

NSP used the Change Momentum Index® to help the leadership team understand where momentum stood at critical points in the rollout — from planning and readiness through go-live, stabilization, and preparation for subsequent deployments.

This gave leaders a clearer view of the conditions shaping adoption.

•Were sponsors reinforcing the change at the right moments?

•Were business stakeholders clear on what was changing and why?

•Were associates ready to move from invoice-driven to PO-driven purchasing?

•Were executive assistants equipped to support new ways of working?

•Were suppliers receiving the clarity needed to adopt the Zycus Supplier Network?

•Were functional teams resolving friction quickly enough to protect momentum?

These questions mattered because Source-to-Pay transformation does not succeed because a platform goes live.

It succeeds when the organization changes how work gets done.

CMI® helped surface the signals that mattered most: where leaders needed to reinforce the change, where stakeholders needed greater clarity, where suppliers required more targeted support, and where associates needed practical help to move from awareness to adoption.

Move the organization

NSP translated momentum insight into targeted leadership and adoption actions.

Working with the CPO, program sponsors, procurement leadership, and functional leads, NSP helped align release milestones, governance routines, stakeholder engagement, communications, training, and adoption support so the transformation could move through the business with less friction.

The work included mapping leadership and stakeholder engagement across each phase of the rollout, clarifying adoption risks, sequencing communications, and ensuring that business readiness was treated with the same seriousness as technical readiness.

A core part of the strategy was the design and management of dedicated Change Champion Networks for the U.S. and Canada rollouts.

These peer-led networks created a practical mechanism for two-way communication, early identification of adoption barriers, and credible advocacy within the business. They gave the program a way to hear what was happening closer to the work — before issues became escalations, delays, or workarounds.

The networks also helped shift the organization from early Acceleration into Momentum.

Progress was no longer dependent only on the central program team. The business began to carry more of the change itself.

Communications were also sequenced by audience and stage of adoption. Associates, executive assistants, and suppliers received clear, action-oriented messaging that connected procurement policy changes, system behaviors, and practical business benefits.

The goal was not simply awareness.

The goal was movement.

Each audience needed to understand what was changing, why it mattered, what action was required, and how to get support when the new process met real operational friction.

Build execution capacity

NSP helped build the structures and routines required for momentum to hold beyond go-live.

The team designed and delivered a blended learning program that included virtual instructor-led sessions, self-paced resources, and structured office hours. These supports equipped users with the knowledge and confidence to adopt PO-driven purchasing while giving the program team a real-time view into where confusion, resistance, or operational friction remained.

Office hours became more than a support mechanism.

They became a momentum signal.

As attendance and support questions declined over time, the pattern indicated that users were becoming more self-sufficient, the new process was taking hold, and the organization was moving from active enablement toward sustained adoption.

NSP also worked with functional leads to resolve adoption barriers in real time — including coding complexity, temporary process exceptions, supplier onboarding challenges, and questions about how the new procurement guidelines applied in practice.

That work mattered because transformation momentum often slips at the point where policy, process, technology, and daily behavior meet.

Resolving friction at the point of adoption helped protect the go-live timeline, sustain stakeholder confidence, and keep the organization moving forward.

The impact: from fragile progress to sustained procurement momentum

The U.S. and Canada rollouts met their critical milestones.

But the more meaningful indicator was the momentum pattern that emerged after launch.

A high percentage of frequent system users established early. Office hours attendance declined. Support questions reduced over time. Associates reported that they felt prepared to use Zycus and had the resources they needed to complete procurement activities with less disruption.

That trajectory — from active enablement to self-sustaining adoption — is the signature of an organization moving from Momentum toward High Velocity on the CMI® curve.

PO-driven transactions increased materially, improving compliance with procurement guidelines and reducing the time required to process purchase orders and invoices through streamlined approvals and front-loaded coding.

These were not incidental gains.

They represented a structural shift in how the procurement function operated.

The qualitative indicators reinforced the quantitative story. Stakeholder alignment held throughout the program, supported by structured governance and consistent, transparent communication. Supplier experience was positive, with clear onboarding communications and early adoption of the Zycus Supplier Network. Functional teams were better able to identify and resolve adoption issues before they became broader program risks.

The transformation did not simply go live.

It gained traction.

Sustaining outcomes: what comes next

The U.S. and Canada rollouts are the foundation, not the finish line.

The program is now preparing for additional international deployments, an updated Chart of Accounts, and expanded catalog capabilities — changes that will further integrate Source-to-Pay across regions and categories.

What makes the next phase different is the organizational capability already in place.

The change networks, governance routines, communications discipline, training infrastructure, and embedded adoption practices are not artifacts of a single rollout. They are the infrastructure of sustained momentum.

They give the enterprise a stronger ability to absorb the next wave of transformation without losing the momentum it has already built.

That is the compounding value of leading transformation with the Change Momentum Index®.

Not just a successful go-live.

A stronger organization for the next transformation.

What this story shows

Source-to-Pay transformation is often measured through implementation milestones, system readiness, transaction volume, supplier onboarding, and process compliance.

Those measures matter.

But they do not tell the full story.

The deeper question is whether the organization is moving with the change.

In this transformation, CMI® helped leaders see where momentum stood, where it needed reinforcement, and what actions would help the organization move from fragile progress to sustained adoption.

That is the difference between a platform launch and a procurement transformation that holds.

Transformation performs when the organization moves with it.
