The most important phase of IT isn’t procurement, it’s implementation

By Chris Lakich, P.Eng, Director, Solutions Delivery, Bell

Where complexity is either managed thoughtfully or allowed to take over 

When organizations plan a major IT or network transformation, procurement tends to receive the most attention.

Platform comparisons. Vendor evaluations. Pricing models.  Approval cycles. 

That focus makes sense. Procurement is visible. It’s measurable. It feels decisive. 

But when you look back at projects that truly succeeded, or quietly struggled, the difference usually wasn’t what was purchased. It was how the technology was implemented. 

In networking especially, implementation is the phase that determines whether strategy turns into something stable and usable, or something fragile that teams spend years compensating for. This is where Professional Services plays a defining role. 

Why implementation carries so much weight 

Networks don’t exist in isolation. They sit beneath everything: applications, security, customer experience and day-to-day operations. When changes happen here, the blast radius can be wide. 

What makes implementation so critical isn’t the hardware or software themselves. It’s the decisions made along the way: 

• • • How closely designs reflect reality 
    • How risk is handled during change 
    • How legacy constraints are managed 
    • How well the operations team is prepared for life after go-live 

These decisions don’t always feel big in the moment. But they shape how the environment behaves long after the project team has moved on. Experienced Professional Services teams are often the ones surfacing these decisions early, before they become embedded problems. 

Where things typically get complicated 

Most networking implementations aren’t derailed by bad intent or lack of effort. They struggle because complexity gets underestimated early on. 

• • • Documentation isn’t current. 
    • Sites aren’t as standardized as assumed. 
    • Dependencies across teams surface late. 
    • Security requirements evolve mid-stream. 
    • Some parts of the network simply can’t be touched during business hours. 

None of this is unusual. 

The question is whether the delivery approach is built to absorb that complexity, or whether it’s forced to react under pressure once the project is already in motion. 

When implementation is treated as a checkbox exercise, teams end up making short-term decisions to keep things moving. Those decisions often stick around far longer than intended and can become ongoing operational debt. 

Procurement chooses technology - implementation shapes outcomes. 

Buying networking technology is a point-in-time decision. Implementing it is a period of continuous learning, adjustment, and trade-offs. 

This is where Professional Services delivery makes a real difference, not because it removes complexity, but because it brings structure to it. 

Strong delivery teams focus less on speed for its own sake and more on making sure the right things are understood early. That usually includes: 

• • • Discovery that goes beyond diagrams 
      Understanding how the network actually behaves, not just how it was designed to behave. 
    • Design grounded in real constraints 
      Translating business, security, and operational realities into something implementable. 
    • Phased, risk-aware deployment 
      Reducing blast radius while allowing room to adjust as lessons emerge. 
    • Tight alignment with security and operations 
      So changes don’t introduce new issues after handover. 
    • Clear ownership and escalation paths 
      Because implementation always raises questions, and unanswered questions slow everything down. 

These elements are not “nice to haves.” They’re fundamental to making the network usable, supportable and resilient once the project team steps away. 

Why “We’ll fix it later” rarely works 

In networking projects, small compromises often feel harmless. A temporary workaround. A rushed configuration. A design choice that prioritizes speed over clarity. 

The problem is that networks remember. 

Those compromises become part of the environment. They affect troubleshooting, scaling, and future change. Months later, internal teams are still dealing with the ripple effects, often without understanding why certain decisions were made in the first place. 

Professional Services brings discipline here: making decisions intentionally, documenting them, and ensuring trade-offs are visible rather than accidental. 

Implementation as a strategic phase 

The most successful network transformations treat implementation as a strategic phase, not a technical afterthought. 

• • • They invest time where it matters early. 
    • They use experienced delivery teams to surface risks before they become problems. 
    • And they think just as much about day-two operations as they do about day-one activation. 

When that happens, procurement becomes what it’s meant to be: a starting point, not the defining moment. 

Making your network investment count 

If an IT or networking investment isn’t delivering the value you expected, the root cause is rarely what you bought. 

More often, it’s how the complexity of implementation was handled. 

Done well, the combination of sound architecture and strong Professional Services can turn technology into real capability. Done poorly, it can turn good technology into ongoing friction. 

That’s why, in networking, implementation isn’t just another phase, it’s the most important one.
