Inter-Dependencies - the Silent Killer of Projects.

Most project delays do not happen because a team failed to do their job. They often happen because that team delivered exactly what they were asked to—and then discovered, too late, that something else they depended on was not ready.

This is the reality of interdependencies: very few projects exist in isolation, but most are managed as though they do.

The cost is not just delay. It's rework, lost trust, budget overrun, and the slow erosion of confidence across leadership, delivery teams, and stakeholders—all caused not by incompetence, but by disconnection.

The Silo Problem.

Everyone knows this one! When a project team is heads-down on their own backlog, their own sprints, their own milestones, it's easy to lose sight of the bigger picture. The focus narrows to "are we on track?"—without asking "are we on track relative to everything else this depends on, and everything that depends on us?"

This is not a failure of effort. It's what happens naturally when teams are structured and measured around their own deliverables, with no-one responsible for the connective tissue between them.

The result: a team can hit every one of their own milestones and still end up labelled "delayed"—because another team, system, vendor, or business unit was not ready, and nobody flagged it until it became a problem.

Breaking down silos is not a cultural initiative—it's a structural and operational one. It requires deliberate design: clear roles, regular touch-points, shared visibility, and someone whose job it is to hold the bigger picture.mes.

The Conduit Role is Critical.

In any complex technology program, one of the most important roles is not technical—it's connective.

The Delivery Manager or Senior Program Manager is the conduit between the project and the organisation. This is not a coordination function. It's a strategic one. The conduit is responsible for:

> Maintaining visibility across all workstreams and their interdependencies.
> Surfacing risks and blockers that exist between teams, not just within them.
> Translating technical progress into business language for senior stakeholders.
> Ensuring that organisation-level changes—restructures, policy shifts, vendor changes, competing priorities—are fed back into the delivery plan before they become surprises.
> Holding the map of how this project connects to everything else.

Without this role operating effectively, information exists in silos. Teams report upward but not across. Risks are identified within streams but not connected across them. And leadership receives status updates that look fine until suddenly they are not.

In a large program, this role may sit with a Program Management Office (PMO). In a smaller delivery environment, it often sits with the most senior delivery leader. Regardless of title, the function must be explicitly assigned—because if everyone assumes someone else is doing it, no one is.

Architecture is Not a Sign-off - it’s a Compass.

Enterprise Architects and Solution Architects are among the most under-utilised resources in project delivery—brought in at the end to review decisions that were made without them, rather than at the beginning to shape decisions that will affect everything else.

Architecture teams sit across the technology landscape by design. They understand how systems connect, where integration points exist, and how a change in one area ripples into another. That knowledge is precisely what is needed when navigating interdependencies—and it is rarely available to project teams who operate in isolation.

Enterprise Architects.

Enterprise Architects hold the organisational view: the roadmap, the platforms, the standards, and the strategic direction. They can identify when a project's technical approach conflicts with the broader architecture direction—or when another initiative is already solving the same problem.

Solution Architects.

Solution Architects operate at the project level, but with a systems-thinking lens. They design for integration, not just delivery. Their involvement in early planning—not just design reviews—means that dependencies are identified before they become blockers.

Network Architects.

Network Architects are often overlooked entirely until a connectivity, latency, or infrastructure issue surfaces late in delivery. Engaging them early—particularly for projects involving cloud migration, distributed systems, or third-party integrations—can prevent some of the most disruptive and hardest-to-resolve delays.

The recommendation is straightforward: architecture teams should be engaged at the start of planning, not the end. Their role is not to approve what has already been decided—it is to provide the organisational and technical context that shapes better decisions earlier.

Security is a Strategic Voice - Not a Gate-keeper.

Invite them to the table!

Security teams occupy a unique position in the organisation. They often have visibility into regulatory requirements, compliance deadlines, audit cycles, and risk thresholds that will affect multiple programs—but that information rarely makes its way into individual project plans unless someone specifically requests it. 

Security reviews that arrive at the end of a delivery cycle can cause significant disruption—not because security is being unreasonable, but because the requirements were known and simply not incorporated early enough.

The solution is to integrate security as a voice in program planning, not a gate at the end. This means:

> Including security representation in architecture and design reviews.
> Sharing delivery timelines with security leads so they can flag known compliance windows or upcoming regulatory changes.
> Building security acceptance criteria into the Definition of Done—not treating it as a separate process.
> Ensuring security assessments are sequenced into the delivery plan with realistic lead times.

When security is engaged as a partner rather than a checkpoint, they become one of the most valuable sources of organisational context available to a delivery team..

Stakeholder Sessions.

One of the most common mistakes in stakeholder engagement is running a single type of meeting that tries to serve too many purposes at once. The result is sessions that are too technical for senior stakeholders and too high-level for delivery teams—satisfying no one and surfacing little of value.

A more effective model separates stakeholder engagement into two distinct session types:

Architecture & Design Reviews.

These sessions are broader in scope and technical in depth. The purpose is to ensure that senior stakeholders—particularly those responsible for technology strategy and organisational direction—understand the architectural decisions being made, the systems being affected, and the dependencies that exist across the program landscape.

Attendees should include enterprise architects, solution architects, security leads, infrastructure owners, and senior technical stakeholders from affected business units. The output is not just a decision—it is a shared understanding of how the pieces fit together.

These sessions do not need to happen weekly, but they should recur at meaningful intervals—at key design milestones, at the start of major phases, and whenever a significant architectural decision is on the table.

Delivery Timeline & Sequence Reviews.

These sessions are focused on progress, sequence, and near-term risk. They bring together delivery leads, project managers, stream owners, and external representatives—vendors, partner teams, dependent business units—to review what’s happening, what's coming, and where dependencies could create problems

The agenda is structured around three questions:

> What has been completed since we last met?
> What is coming in the next sprint or period—and what does it depend on?
> What risks or blockers exist that this group needs to know about?

A shared dashboard—visual, real-time, and accessible to all—should anchor these sessions. Not a slide deck prepared for the meeting, but a live view of status, sequence, and dependency that the group can discuss together.

Workaround or Wait?

When an interdependency gap surfaces—a dependency that is not ready, an integration that can not be completed, a team that is not able to deliver on the expected timeline—there is an immediate decision to be made: implement a workaround, or delay and wait for the dependency to resolve.

This decision is often made too quickly, too emotionally, or too locally. The delivery team under pressure defaults to the workaround because waiting feels like failure. But not all workarounds are equal—and a poor workaround can create more technical debt, rework, and downstream risk than the original delay would have.

The right assessment considers:

Effort vs. Value.

How much work is the workaround? If it's a meaningful engineering effort, is that effort better spent on delivery that advances the program rather than patching a gap that will eventually be resolved anyway?

Reversability.

Can the workaround be cleanly removed or replaced when the dependency is ready? Or does it embed itself into the architecture in ways that create long-term complexity?

Risk Introduction.

Does the workaround introduce new risk—to security, stability, performance, or compliance—that did not previously exist?

Time Impact.

Will implementing the workaround actually save time when the full effort is considered, including testing, documentation, and eventual removal?

This assessment should involve the conduit, the relevant architect, and where appropriate, the security or infrastructure lead—not just the delivery team. The decision should be documented, owned, and reviewed as a formal program decision rather than a local tactical call.

Sometimes a workaround is absolutely the right call. Sometimes the most disciplined decision is to hold the dependency and protect the integrity of what follows. The point is to make that call deliberately, with full information, rather than under pressure.

Breaking Down Silos.

Silos do not break down because someone announces a cultural change. They break down when the structures, rhythms, and incentives that created them are replaced with ones that reward connection and shared accountability. Here are the approaches that work:

Assign Cross-functional Accountability.

The conduit role exists for this purpose—but it should be reinforced by making interdependency management a visible, measured responsibility, not an informal expectation.

Create a Shared Program View.

A single dashboard that shows all active workstreams, their status, their dependencies, and their sequence—visible to everyone, updated continuously, and used as the reference point in every stakeholder session. When everyone is looking at the same picture, conversations change.

Rotate Representation.

Invite engineers, architects, and security leads into delivery review sessions—not just their managers. Direct exposure to the broader program creates organic awareness of interdependencies that no report can replicate.

Make it Safe to Raise Blockers.

Teams stay silent about dependencies when raising them feels like admitting failure. The program rhythm should actively reward early flagging of risk—treating it as valuable intelligence, not a sign of underperformance.

Connect Delivery to Organisational Outcomes.

When teams understand how their work fits into the broader mission—not just their own sprint goal—the motivation to look left and right, not just forward, increases naturally.

Replace Email with Conversation.

Status emails get skimmed. Risk flags buried in a report do not prompt action. A regular meeting—with intent, a shared dashboard, and the right people in the room—surfaces what email never will.

The One-Tea m Mindset.

Fostering a one-team, whole-of-organisation vision does not mean everyone needs to understand every detail of every other project. It means creating a regular, structured space where the right people can flag the right things before they become problems—and where "how does this affect everyone else?" is a question that gets asked as a matter of course.

The organisations that deliver complex technology programs successfully are not the ones with the best individual teams. They are the ones where those teams are connected—by clear roles, shared visibility, regular conversation, and a conduit who holds the map.

Projects do not get delayed because people are not working hard enough. They get delayed because they are disconnected.

The fix is structural, deliberate, and entirely within reach.
