Creating a resource plan across multiple projects

Managing resources across several projects is a common challenge for programme and portfolio leaders. Competing priorities and shifting timelines can quickly create pressure, especially when capacity is limited.

While individual project planning may be well structured, coordinating resources across multiple initiatives requires a broader perspective. Without this, teams can become overstretched and delivery can slow, which often leads to inefficiencies building over time.

A structured approach to resource planning helps organisations maintain control. It directs effort towards the areas where it has the greatest impact and supports more consistent delivery across the portfolio.

Understanding resource demand across the portfolio

Effective planning begins with a clear view of demand. This means understanding what each project requires and when those resources are needed.

At portfolio level, this often involves comparing multiple timelines and identifying where requirements overlap; these overlaps can create pressure points, particularly where specialist skills are involved.

Visibility is essential. When demand is clearly mapped, it becomes easier to identify potential constraints before they affect delivery, allowing leaders to make informed decisions about prioritisation and scheduling.

Regular review also plays a role. As projects evolve, demand may change, so keeping this view up to date ensures that plans remain relevant and responsive.

Factors that impact resource prioritisation

Prioritising resources based on organisational value

Not all projects carry the same level of importance. Some will contribute more directly to strategic objectives, while others may support operational improvements.

Prioritisation supports the effective allocation of limited resources. This involves assessing projects in terms of their contribution to organisational goals and the value they are expected to deliver.

Aligning with strategic priorities

Projects that support key objectives should be given appropriate focus, reducing the risk of critical initiatives being delayed due to competing demands.

Clear alignment between projects and strategy also supports decision-making. When trade-offs are required, it becomes easier to determine where resources should be directed.

Balancing short-term and long-term needs

Resource planning should consider both immediate delivery requirements and longer-term capability. Focusing only on short-term needs can create gaps in future capacity.

Maintaining this duality frees up the organisation to respond to changing priorities without compromising ongoing work.

Avoiding overallocation and inefficiency

Overallocation is one of the most common issues in multi-project environments. When individuals or teams are assigned to too many tasks, productivity and morale decline causing quality to suffer.

Inefficiency can also arise when resources are not used effectively. This may occur when skills are mismatched to tasks or when work is delayed due to dependencies.

A proactive approach can reduce these risks:

• Monitor workload to ensure individuals are not assigned beyond realistic capacity
• Match skills to tasks so that work is completed efficiently
• Identify dependencies early to prevent delays

These steps support better utilisation of resources and help maintain steady progress across projects.

Planning for constraints and changing demand

Constraints are a constant factor in resource planning. Availability, budget, time and skills all influence what can be achieved at any given moment.

Rather than reacting to constraints as they arise, effective planning anticipates them. This begins with understanding where limitations exist and how they may affect delivery. For example, limited access to specialist skills can create delays if not managed early.

Scenario planning can support this process. By considering different demand levels, organisations can prepare for changes in workload without disrupting progress, helping to create flexibility within the plan while maintaining control.

It is also important to build contingency into resource plans. Allowing for some flexibility means unexpected changes can be managed without placing additional pressure on teams.

Establishing clear communication channels

Regular updates support alignment. They provide an opportunity to review demand, identify emerging issues and agree adjustments where needed.

It is this consistent communication that helps to ensure resource decisions are visible across the portfolio. Project managers need to understand how their plans affect others and where dependencies exist.

Using central oversight

A central view of resources allows programme and portfolio leaders to maintain control. This can be supported through a Project Management Office or similar governance structure. With clear oversight, it becomes easier to identify imbalances and take corrective action so that resources are used effectively across all projects.

Strengthening resource planning capability

Creating an effective resource plan across multiple projects requires both structure and judgement. By improving visibility, prioritising based on value and managing constraints proactively, organisations reduce pressure and improve outcomes.

For professionals working in programme and portfolio environments, these skills are essential. Our PRINCE2® Programme Management and PRINCE Portfolio Management courses provide structured guidance that supports resource planning at scale.
