The Brief
Following an unsuccessful OneStream implementation, our client required a highly specialised professional who could stabilise the platform and unlock its intended value. This was not a typical systems implementation role. The organisation needed someone who could bridge finance and technology, act as an internal advocate for the system, and engage confidently with senior stakeholders and external consultants.
Given the niche nature of the requirement and the business-critical impact, the assignment was delivered on a retained basis, enabling a targeted, high-quality search approach, allowing Altum Consulting to prioritise this search within their workload.
The Challenge
The organisation faced several interconnected challenges:
- A previous OneStream implementation had failed, with limited clarity around the root causes.
- Ongoing system issues were placing operational strain on the finance team, who were compensating for functionality gaps.
- There was a skills and ownership gap, with no internal expert to lead system governance or optimisation.
Our client required a specialist capable of combining deep technical expertise, finance knowledge, and the ability to influence stakeholders, this made the role particularly challenging to source through traditional methods.
Our Approach
Altum Consulting conducted a targeted retained search, supported by market mapping across organisations with active OneStream programmes and similar finance transformation environments.
Our focus was on identifying candidates with:
- Proven experience in OneStream configuration and system setup
- Strong knowledge of data integration, governance, and controls
- A background bridging finance operations and technology
- The ability to influence senior stakeholders and act as an internal system champion
We also prioritised candidates who had experience recovering or optimising complex implementations, ensuring the individual could deliver both immediate stability and long-term improvement.
The Outcome
The role was successfully placed with a highly qualified specialist.
The successful candidate was sourced from a OneStream Diamond Partner, bringing recognised expertise and market credibility. Our client gained a dedicated internal owner capable of stabilising the platform, partnering with consultants, and driving adoption across the finance function.
This assignment demonstrates Altum Consulting’s ability to deliver niche, transformation-critical finance systems talent through a retained, research-led approach. The engagement also created a clear market map of similar OneStream programmes, supporting future hiring strategies and enabling targeted outreach to organisations facing comparable challenges.
