How Horizontal Lean Portfolio Management Can Turn Shared Services Into Strategic Enablers

Lean Portfolio Management (LPM) is more than a process or framework. It’s the strategic lever that allows organizations to move as fast as opportunity demands by transforming how decisions are made, funding is allocated, and value is delivered across the enterprise.  

Today’s fastest advancing enterprises understand a critical truth: team-level agility alone isn’t enough. If the portfolio can’t move, strategy stalls, investments underperform, and opportunities slip away.  

LPM creates the strategic guardrails that connect enterprise priorities to execution, ensuring decisions and funding stay aligned with business outcomes. Through disciplined, continuous prioritization, leaders gain clear visibility into work in flight, ownership, and value realization, allowing them to proactively reallocate capacity and focus on the highest-impact initiatives. 

In practice, however, many organizations encounter a critical constraint when putting this model into action with shared services. 

The Value-Aligned Enterprise: Vertical LPM and Technology “Slices” 

Within an agileLPM model, technology is aligned to business value streams, or “vertical” portfolios. Each vertical manages funding, prioritization, and governance, allowing teams to operate independently while staying aligned to enterprise strategy.  

This approach is highly effective—until it intersects with shared services. 

Unlike verticals, shared services are cross-cutting “horizontals” that provide centralized expertise and standardized capabilities across the enterprise. They own foundational functions that ensure operations remain secure, reliable, and efficient, including: 

• Architecture 

• AI  

• Cybersecurity 

• Cloud & infrastructure 

• DevOps / platform engineering 

• Testing & quality engineering 

Although these groups are critical to enterprise success, they often struggle to find their place in a value-aligned LPM model, which can make coordinating demand, priorities, and delivery across verticals challenging. 

Why Shared Services Don’t Fit Neatly into Traditional Agile LPM Model 

Supporting multiple vertical portfolios simultaneously puts shared services in a constant balancing act. Instead of accelerating value, they risk becoming bottlenecks. 

Several common challenges create this tension: 

1. Competing Priorities and Constant Escalation: Every vertical portfolio believes its needs are the highest priority. Without a mechanism to compare value across portfolios, shared services leaders spend their time arbitrating conflicts rather than enabling delivery.
2. Waterfall Work in Agile Ecosystems: Shared services are often last to adopt agile ways of working. Sequential hand-offs, late-stage reviews, and rework slow down the very value streams LPM is supposed to accelerate.
3. Reactive Decision-Making: Many shared services plan around incoming requests rather than strategic funding, leading to fragmented resourcing and inconsistent prioritization. Without a strategic backlog of their own, these teams are forced into a reactive mode. They respond to immediate demands instead of proactively building capabilities that advance the enterprise’s long-term goals.
4. Inconsistent Operating Models: Different verticals ask for different things in different ways. Shared services morph to meet each demand, undermining the reason they exist: consistency, standardization, and efficient reuse. 

 In other words, LPM works for shared services only when shared services also have LPM framework. 

 Horizontal LPM: The Missing Framework for Shared Services 

Horizontal LPM introduces the same level of discipline, governance, and strategic clarity to shared services that vertical portfolios enjoy. It gives these teams a structured framework to align investments, priorities, and execution across the enterprise. 

Done well, Horizontal LPM delivers: 

1. Clear Governance and Visibility: Leaders gain insight into the demand patterns, dependencies, and capacity constraints of shared services, enabling more confident portfolio-level decisions.
2. Standardized Ways of Working: Shared services operate consistently across all verticals, reducing friction and improving predictability.
3. Strategic Alignment: Shared services shift from cost centers to value-driving partners. Their work becomes purposeful, funded, and measured, rather than an endless queue of disconnected requests.
4. Faster, More Predictable Delivery: With their own backlog, roadmap, and planning cadence, shared services can build ahead of demand and proactively meet enterprise needs. 

What Horizontal LPM Looks Like in Practice 

In a horizontal model, shared services no longer act as a series of tasks to be completed within someone else’s project. Instead, they operate as true product and platform teams with their own roadmaps, priorities, and measures of value. This shift fundamentally changes how work is delivered across the enterprise. 

Quality engineering, for example, evolves from a late-stage testing activity to a fully realized quality platform. One that enables teams with reusable patterns, tools, and continuous testing capabilities. Cloud and infrastructure teams follow suit, moving away from bespoke configurations to scalable, standardized platforms. Cybersecurity also transforms, shifting from individually reviewing every unique request to developing reusable security products that provide both speed and safety. 

As Horizontal LPM matures, shared services naturally begin to develop self-service capabilities and scalable, reusable solutions. By planning alongside vertical portfolios, they gain early visibility into common needs, align with business timing, and can make realistic commitments that reduce bottlenecks and prevent downstream rework. 

This transformation elevates shared services from operational cost centers to strategic accelerators. With clear insight into demand, capacity, and value, their products and platforms can be intentionally prioritized and funded as enterprise-level enablers. Rather than reacting to scattered requests, shared services become proactive builders of capabilities that drive agility. 

Transforming Cybersecurity Through Horizontal LPM 

One of our clients’ cybersecurity teams sought to move from a reactive operating model to a more strategic, platform-oriented approach. As the business grew and vertical portfolios adopted LPM, the team faced increasing cross-portfolio requests. While they consistently delivered high-quality work, much of it was reactive rather than planned. Leadership saw an opportunity: by adopting a proactive, platform-focused model, cybersecurity could better enable the enterprise and contribute strategically to value delivery. 

 Two Roads partnered with the team to design a Horizontal LPM model tailored to their needs. We established a standardized intake and prioritization process, co-developed a cybersecurity product roadmap emphasizing scalable platforms and reusable patterns, and aligned planning cycles with vertical portfolios to anticipate demand and shape commitments proactively. 

 The results were transformative. With clearer priorities, consistent operating rhythms, and a shared roadmap, the team gained the ability to allocate resources intentionally, invest in enterprise-level capabilities, and improve both agility and predictability. Most importantly, cybersecurity evolved from a reactive support function into a proactive enabler, accelerating delivery across vertical portfolios and driving strategic enterprise outcomes. 

Horizontal LPM Unlocks the True Power of Agile at Scale 

Relying on shared services to participate in vertical LPMs without their own LPM structure limits their ability to operate strategically and often results in reactive, inconsistent delivery models. Horizontal LPM changes that dynamic. It provides shared services with the clarity, governance, and strategic alignment necessary to deliver value and operate as true product and platform organizations, aligned to enterprise strategy instead of individual requests. 

For organizations aiming to unlock true end-to-end agility, adopting Horizontal LPM may be one of the most impactful steps they can take.
