Interim Manager as Interface Manager: Turning Consulting Insights into Action

In the dynamic world of business transformation, interim managers have long played a vital role in turning strategic recommendations into operational reality. Traditionally, companies hire interim managers after engaging top-tier consulting firms that provide well-researched strategies, process optimizations, and organizational recommendations. However, once the consultants leave, businesses often face a significant challenge: converting recommendations into real, sustainable results.

An interim manager doesn’t simply “take over” where consultants have left off; they function as an interface manager, bridging gaps between strategy and execution, project phases, or even internal and external processes. My experience suggests three distinct ways this interfacing role becomes critical: project-to-process, process-to-process, and project-to-project transitions. Each presents unique challenges requiring management skills, a thorough organizational understanding, facilitation, and coaching.

From Project to Process: Redefining Deliverables for Real Value

One of the most common situations I encounter is when a company hires a consulting firm and receives a detailed report but struggles to determine what to do next. The consulting firm acted with the best intentions, but the client failed to establish clear expectations for tangible outcomes.

The Problem: Unclear Deliverables and Unprepared Clients

• The company assumes that the consulting firm will outline the following steps. In contrast, the consulting firm expects the client to carry out the recommendations.
• Consulting outputs are often overly theoretical, lacking connections to current business systems or operations.
• Client-side managers frequently lack the clarity or confidence to identify their true needs.

Interim Manager’s Role: Turning Abstract Recommendations into Actionable Deliverables

When stepping into this situation, the first step is often a deliverable reset. This involves:

1. Clarifying the Intended Outcomes – What is the business genuinely trying to achieve? Often, this discussion does not occur until after consultants are engaged.
2. Facilitating Alignment Among Stakeholders – Many managers struggle to articulate their expectations, resulting in misalignment. Structured facilitation workshops effectively translate strategic recommendations into operational needs.
3. Redefining Deliverables in Business Terms – Transforming PowerPoint presentations and conceptual models into tangible project roadmaps, KPIs, and process adjustments.
4. Bridging the Execution Gap – Ensuring the organization has the appropriate internal resources, skills, and tools to move forward without ongoing external support.

Why don’t consulting firms support this?
Because it reveals a disconnect between their compensation and the company’s actual needs, it necessitates transitioning from abstract consulting deliverables to tangible business outcomes.

From Process to Process: Managing “Irreplaceable” Consultants and Knowledge Transfer

Another common challenge occurs when companies have long-term external consultants deeply integrated into their operations. These consultants often possess critical process knowledge, making them seem “irreplaceable.” Businesses fear losing them, resulting in constant contract extensions and increasing dependency.

The Problem: Dependency on External Consultants

• Long-term consultants become gatekeepers of knowledge, preventing smooth transitions.
• Key process details exist only in their heads—no structured documentation.
• Internal employees lack the expertise or confidence to take over.
• Companies struggle to phase out expensive external consultants without causing operational disruptions.

Interim Manager’s Role: Structured Knowledge Transfer & Transparent Progress

In these cases, the role of an interim manager is to break down knowledge silos and ensure sustainable internal ownership. This involves:

1. Systematically Extracting Knowledge – Conducting structured interviews, documentation sessions, and process mapping workshops to capture and record vital insights.
2. Creating a Clear Transition Plan – Ensuring knowledge transfer is a visible, organized process rather than an ambiguous promise.
3. Building Internal Capabilities – Developing training programs, shadowing sessions, and mentorship structures to empower employees.
4. Preventing Further Consultant Lock-In – Establishing clear transition timelines and contractual expectations to prevent indefinite extensions.

Why is this difficult?
Because these consultants have a vested interest in maintaining their roles, they resist structured knowledge transfer, making it essential to manage the process with discipline and transparency.

From Project to Project: Moving Beyond PowerPoint-Driven Consulting Projects

One of the most frustrating project situations I’ve encountered is when a large consulting firm manages an entire project through PowerPoint presentations. Despite having robust IT systems, data analytics platforms, and project management tools available, consultants keep all their work in decks, updates occur only in scheduled meetings, and no real execution framework exists.

The Problem: A Project That Only Exists in Slides

• The project’s true progress relies on the upcoming PowerPoint presentation rather than concrete milestones.
• No effort is made to incorporate solutions into current business systems.
• The company has a pile of documents but lacks a structured implementation plan.
• The consulting firm remains indispensable because no one else understands the project.

Interim Manager’s Role: Integrating Project Work into the Organization

Taking over a project like this requires shifting from slide-based execution to real operational integration:

1. Breaking the PowerPoint Cycle – Transitioning deliverables into structured project tools, data systems, and execution frameworks.
2. Creating a Lightweight Internal PMO – Ensuring the organization has internal ownership of project tracking, governance, and decision-making.
3. Integrating Work into Business Processes – Aligning projects with company-wide IT systems, dashboards, and workflows to incorporate them into daily operations.
4. Ensuring Knowledge Stays Within the Organization – Documenting methodologies and providing hands-on training to internal teams.

Why do consulting firms resist this?
Because it eliminates their ongoing control over the project and transfers ownership back to the company.

Final Thoughts: Why the Role of an Interface Manager is Critical

Each scenario highlights the fundamental challenge of consulting engagements: the gap between strategic recommendations and real-world implementation. Without clear deliverables, knowledge transfer, and operational execution, consulting projects often fail to provide sustained value.

This is where an interim manager as an interface manager becomes indispensable:

✔ Bridging the gap between consulting deliverables and business needs.
✔ Ensuring structured knowledge transfer to prevent long-term external dependencies.
✔ Transitioning from PowerPoint-based management to operational execution.

Executives investing in consulting services must recognize that hiring a consulting firm is the first step. Ensuring that insights turn into real impact requires structured interfacing, disciplined execution, and, in many cases, the presence of an experienced interim manager.

Suppose you’ve found yourself in one of these situations. In that case, it might be time to bring in an interface manager who can transform recommendations into reality.
