Background and Use of Scenarios within Workforce Planning

By Tanya Hammond, Wendy Morison, Jaye Matheson and Tessa Spinks

Scenario planning is a strategic technique that helps organisations prepare for the future by exploring multiple plausible outcomes.  In the context of workforce planning (WFP), a scenario is defined as a “hypothetical, but plausible, story about future events constructed from observed trends and historic data” (CSIRO, 2012). Rather than trying to predict one definitive future, scenario planning allows HR professionals and business leaders to consider a range of alternative futures for the organisation and their workforce.  This approach helps organisations address the key question:

“What does our organisation need from its workforce to successfully deliver its business goals now and into the future?”

Scenario planning acknowledges that the future cannot be forecast with absolute certainty and there is no single ‘best way’ that will remain optimal. Instead, it encourages flexibility and forward thinking. As strategy expert Charles Roxburgh noted in regard to scenarios:

“Although it is surprisingly hard to create good ones, they help you ask the right questions and prepare for the unexpected. That is hugely valuable.”

In other words, the value of scenarios lies not in predicting exactly what will happen, but in prompting decision-makers to think broadly and prepare for what might happen.

In workforce planning, we develop scenario narratives to describe the potential future states of the organisation. These narratives are used to inspire decision makers to envision the impacts of key drivers of change on the organisation and its workforce. Scenario planning is a qualitative technique that complements quantitative forecasting by capturing insights beyond what historical data trends alone might suggest. It enables organisations to explore ‘what if’ situations and to identify how different factors could create different workforce and workplace needs. Ultimately, scenario planning in WFP provides a basis for formulating people management strategies that are robust under a variety of future scenarios, thereby helping mitigate future workforce-related risks:

Figure 1: Scenario Planning Horizons illustrates the importance of scenario planning in workforce strategy. It shows how scenarios help in considering plausible organisational futures over a five-year period. The various factors such as employee experience, economic, environmental, labour market and technological drivers are key considerations to ensure the organisation is strategically responsive over the timeframe of the workforce plan.

Why Use Scenarios in Workforce Planning?

Using scenarios in workforce planning helps organisations understand variability in their operating environment and prepares them to meet future workforce needs under different circumstances. Traditional workforce planning often relies on a single predicted future without consideration for what is probable, possible or plausible. (e.g. one set of economic assumptions, one forecast of retirements, etc.). However, this can be risky because the real world might diverge from those assumptions. Scenario planning introduces disciplined imagination into planning:

In short, scenario planning adds significant value to workforce planning by broadening the planning horizon beyond the “most likely” future. It helps answer not just where we are headed, but what if things change? – ensuring that the organisation’s workforce strategy is robust, agile, and future-ready.

How do we conduct scenario planning as part of a workforce planning project?

The following outlines a structured approach that we have found effective in our workforce planning projects:

Identify key drivers of change, define continuums and assumptions. 3. Construct plausible outcomes by refining scenario outlines. 4. Combine outcomes with context to create detailed scenario narrative. 5. Validate and finalize the most plausible scenario and workforce impacts.

By following these steps, the scenario planning process becomes systematic and actionable. It ensures that scenario development is not just a theoretical exercise but a practical component of strategic workforce planning, directly feeding into workforce strategies and actions.

Why we focus on the “Plausible Futures”: The “Futures Cone” Concept?

The diagram has dimensions of potential on the vertical axis and time on the horizontal axis, demonstrating how potential scenarios develop into probable and plausible ones as time progresses.

Figure 2: Futures Cone

Not all imagined futures are equally useful for planning – hence the need to focus on plausible scenarios. The Futures Cone is a model that defines different “zones” of the future relative to now, based on levels of certainty and evidence. As time moves forward from the present moment, our certainty about the future diminishes, expanding the cone of possibilities. In workforce planning scenario development, understanding these distinctions helps maintain a balance between creativity and credibility:

Probable Future:

The probable future represents what is most likely to happen if current trends continue uninterrupted. It is essentially an evidence-based forecast – the future we’d expect by extending known historical data and assuming no big surprises. In some situations, an organisation’s probable future can be determined with reasonable confidence (for example, if an industry is very stable or change is slow). In such cases, a single forward projection may suffice for planning. However, in many workforce planning cases, especially strategic ones, data limitations make precise forecasting difficult. There often isn’t enough reliable historical data on workforce variables, or the future conditions might differ qualitatively from the past (think of how remote work adoption in 2020 broke away from past trends). Therefore, relying only on the probable future might give a false sense of certainty. If you do make a single forecast, it should be clearly labelled as probable, not certain.

Plausible Future:

The plausible futures are where scenario planning efforts are best focused. Plausible futures are those that could happen, given what we know today. They may not be the expected outcome, but they have a logical narrative and some backing from trends or experts. This space lies between the predictable probable and the speculative possible. In workforce planning, plausible scenarios combine evidence with imagination. For example, you might envision a scenario where a new technology significantly changes how work is done – there’s evidence the tech is emerging, though it’s not guaranteed to advance that quickly; imagining its impact fills in the gaps. Plausible scenarios should be challenging yet believable, stretching the organisation’s thinking without breaking it. Working in this space yields a set of scenarios (usually 2-4) that are distinct, internally consistent and supported by data points or logical assumptions. This balance ensures each scenario demands a unique response from the organisation, thus testing the robustness of workforce strategies, while still being taken seriously by stakeholders.

Possible Future:

The possible futures encompass everything that could conceivably happen, no matter how outlandish. This is a realm of unlimited imagination – from extreme events to science fiction scenarios. While it’s important to acknowledge that wildcards (low-probability, high-impact events) can occur, planning directly for the entire space of possible futures is not practical. Scenarios that drift into the purely possible space often lack credibility and utility. Without some evidence or logical linkage, you can end up with scenarios that stakeholders dismiss as unrealistic. Moreover, working with too many wildly different scenarios can overwhelm the planning process and lead to analysis paralysis. For workforce planning, we avoid the extremes of the possible realm; for example, a scenario where “suddenly 90% of jobs are done by robots next year” would be too implausible (not grounded in any current trend) to be useful. In summary, the possible future space is theoretically limitless, but strategic planning focuses on a narrower band that’s actionable.

In our approach, after identifying key drivers, we refine the scenario narratives to stay within the plausible zone. The futures cone serves as a mental check: Are we too close to the “probable” (just minor variations of today)? If so, we should be more imaginative so we aren’t blindsided by change. Or are we drifting into “possible” but not plausible (science fiction territory)? If so, we need to pull back to realism. By focusing on the plausible middle ground, the resulting scenarios strike a practical balance. They provide enough diversity to explore different strategic responses, yet enough credibility that leaders will genuinely consider them when making decisions.

 

To summarise, the probable future is what we think will happen, the possible futures include everything that could happen, and the plausible futures are what might actually happen and are worth preparing for. Effective scenario planning for workforce planning lives in that plausible space – it’s where imagination is guided by insight. Staying in this space ensures the scenarios remain useful tools rather than just storytelling exercises, and it maximises their value in informing workforce planning.

 

Following are worked examples of what we typically develop:

A table titled 'Worked Example 1: Prioritized Driving Forces Aligned to Key Uncertainties, Extremities and Plausibility' with columns labeled 'Agreed Driving Forces', 'Key Uncertainties', 'Least Extreme', 'Most Plausible', and 'Most Extreme'. The table lists various topics under 'Cyber Security Threats', 'Economic Downturn', and 'Labour Market Challenges' with detailed descriptions for each.

The table has three main sections: Technology Adoption, Economic Downturn, and Labour Market Challenges. Each section describes key uncertainties, least extreme and most extreme scenarios, and the applicable strategic responses, including a 3-year AI and machine learning adoption, a 20% workforce reduction, and a contingent workforce.

We utilise the most plausible scenarios to prepare a description of the overall scenario which we circulate with key stakeholders to seek their input and signoff. An example of a scenario we have utilised in workforce planning is as follows:

By focussing on the most ‘plausible’ scenario, organisations can better understand the variability within their environment and gain value from articulating the workforce required. A plausible scenario, with a reasonable amount of detail (e.g. percentages, timeframes etc.), enables organisations to be able to be responsive to anticipated changes in their environment, to be agile, and to plan flexibly to ensure they have the required workforce when it is needed.

A further example scenario that a public sector organisation might develop as part of its workforce planning. This scenario is entirely plausible based on current trends:

Scenario 2028 – “Digital Transformation Boom”:

Over the next five years, rapid advancements in technology and a strong political mandate for digital government services transform how the department operates. By 2028, automation and AI have been integrated into 40% of business processes, eliminating routine administrative tasks. The organisation’s services are now delivered predominantly online and citizens expect 24/7 digital access. This shift has two major workforce implications: first, a surge in demand for IT skills (developers, data analysts, cybersecurity experts) leading to intense competition for talent in these areas; second, many traditional roles have evolved, with employees needing to interpret AI outputs and focus on complex, human-centric work. The workforce is leaner but more specialised – total headcount is 10% lower than in 2023, largely due to attrition and automation, but the number of data specialists has tripled. The organisation has retrained a quarter of its staff in new digital capabilities yet still faces a skills gap in emerging technologies (e.g. AI ethics advisors, machine learning engineers). Employee demographics have also shifted: flexible work and a tech-savvy image helped attract younger talent, so the workforce now spans a broader age range with an influx of early-career professionals. However, the pace of change has led to stress and burnout in some teams, prompting the HR team to bolster wellness and resilience programs. In this scenario, the key risk is failing to keep up with tech innovation – the organisation continually partners with private tech firms and upskills its people to avoid obsolescence. It has also revamped its recruitment and onboarding to compete with the private sector, including offering remote work options and mid-career training fellowships to draw necessary talent.

Workforce Planning Implications (for “Digital Transformation Boom”):

In this scenario, the organisation would need to aggressively invest in upskilling programs to transition existing staff into new roles (e.g. training program administrators to become data analysts). Recruitment strategy would focus on attracting high-tech talent, possibly by revising compensation structures or offering unique value propositions (such as meaningful public service projects with cutting-edge tech). Succession planning becomes critical in IT and data roles as those are now mission critical. The organisation might create new job classifications (e.g. Automation Coordinator, AI Ethics Officer) to formalise roles that have emerged. Conversely, some traditional roles might be phased out or combined. The HR team would also need to manage morale and change fatigue by working closely with leadership to pace the implementation of technology and to support employee well-being. Finally, HR policies around remote work and continuous learning would be key enablers in this future – allowing the organisation to tap into a geographically dispersed talent pool and keep employees’ skills current.

The scenario above is one of the “alternative futures” an organisation might prepare for. Another contrasting scenario (not detailed here) could envision a slower pace of technological change coupled with budget cuts, resulting in a very different set of workforce challenges. By comparing Scenario A (high-tech growth) and Scenario B (stagnation and austerity), the organisation can see a spectrum of challenges and strategise accordingly. The takeaway is that each scenario will highlight different workforce needs and strategies, and by considering them now, the organisation can create plans to address each possibility or a blend of them.

Using Scenarios to Inform Workforce Planning

Developing scenarios is only half of the equation – the real payoff comes from using those scenarios to shape and test your workforce plan. Here are some best practices on how to apply scenario insights:

By actively using the scenarios in these ways, the organisation moves from planning to preparedness. The workforce plan becomes more than a set of static predictions – it becomes a living strategy with built-in agility. This ensures that as the future unfolds (whether or not it’s the one you expected), the organisation is not caught off guard. Instead, you have already visualised the potential challenges and have response strategies ready for implementation.

Best Practices and Considerations for Effective Scenario Planning

When developing and applying scenarios in workforce planning, keep in mind the following tips and considerations to maximise effectiveness:

By following these best practices, scenario planning will be more effective and credible. It transforms from an abstract exercise into a powerful tool that drives strategic decision-making in workforce planning.

Conclusion

In practice, the scenarios developed should continuously inform and challenge your workforce plans. They should be revisited and revised as new information becomes available – scenario planning is not a one-off task but an ongoing mindset. With leadership support and integration into the planning cycle, scenario thinking can become part of the organisational DNA.

In summary, using scenarios within workforce planning enables more robust, flexible, and future-proof HR strategies. It helps the organisation not only to survive in different future states, but to thrive by being proactive and prepared. As the saying goes, “The best way to predict the future is to prepare for it”.  Scenario planning offers a structured approach to preparing for multiple futures. Whether the future brings a digital boom, a demographic shift, or an unforeseen crisis, the organisation’s workforce will be equipped to deliver on its mission.

Scenario planning is a cornerstone of strategic workforce planning in an unpredictable world. By initially developing multiple plausible futures, organisations equip themselves to navigate change with agility. The process of scenario development – from scanning the environment, to crafting narratives, to analysing implications – deepens understanding of the forces shaping the workforce. It pushes leaders to consider “What would we do if…?” and to devise strategies that are resilient under various outcomes.

For any organisation, embracing scenario planning means acknowledging that the only constant is change. The workforce you have today is not the workforce you will need tomorrow and the conditions around you can shift rapidly. Scenarios, as detailed in this paper, act as rehearsals for the future. They won’t predict exactly what happens, but they will help you prepare for whatever happens.
