Retail planning was once built around seasons: back-to-school, holiday shopping and spring resets. Today, consumer demand is more fragmented and less predictable. A product can spike overnight from a viral reel, sell out in one region while untouched in another, or surge online while dormant on the physical shelf.

These shifts strain traditional retail planning models. Many retailers still rely on longer merchandising timelines and outdated seasonal assumptions, leaving teams scrambling to react after demand has already changed. But some retailers are beginning to move faster. They’re combining internal and external demand signals with new technologies to move beyond historical analysis and make faster, more market-aligned planning decisions.

In a recent interview , Matt Hopkins, product marketing for retail and supply chain at Board, noted that the planning challenge can be traced to an evolution that hit overdrive in recent years.

A new wave of signals is here

Digital transformation in Retail has been driving the shift from seasons to signals for decades — each new channel adding a layer of complexity that most retailers never fully resolved. Omnichannel brought managing inventory, pricing and promotions across online and in-store, while mobile added a new element of anytime, anywhere retail.

“Shopping journeys became digital, 24/7 and with multiple touchpoints,” Hopkins said. “You can interact and transact with a brand pretty much at any moment. Most retailers aren’t in a place to capture all the inputs of a digital-native shopping experience.”

Social media takes this need for constant adjustment to a new level. According to GWI’s 2026 Connecting the Dots research, social media has become the dominant media form in consumers’ lives. And the Business of Fashion/McKinsey State of Fashion 2025 report noted that videos tagged #fashion on TikTok have increased 2.5 times in three years, and search volumes for trending styles can fluctuate by 300% over a single 12-month span. The commercial implications for retail planning are significant, and largely unresolved.

Hopkins explained that there’s enough historical social data now to understand the shape of an influencer-driven uplift, much like planners learned to model the impact of a promotion. But most retailers are still treating this as a separate problem.

“The good news is that the signals from social media and influencer activity exist and are increasingly readable. But a lot of retailers are still looking at social media as a completely separate data set,” Hopkins said. “The mistake is that it’s actually just one customer journey — just done across different channels and interaction points.”

Planning for the full picture

Consumer trends and social media activity are one critical signal in a much broader picture. The challenge is that most retailers struggle to view them in coordination with everything else that shapes planning decisions: economic conditions, supplier lead times, competitor pricing, regional demand variations, sales history and inventory positions. Each signal matters. But when they live in disjointed systems and silos, seeing the full picture is nearly impossible.

A unified planning platform brings external signals and internal data into a single environment where the connections between a shifting consumer trend, a regional inventory position and a pricing decision can be seen and acted on.

Applying AI to retail planning

Gaining a unified view also opens more possibilities for applying AI. As Hopkins noted, “If you give AI fragmented data, you’ll get fragmented results.” But when consumer trends, economic signals and internal data all live in the same environment, AI can process them together in a way no planning team can do manually.

According to Hopkins, AI changes what’s possible in three distinct ways. It identifies where the plan is at risk before it becomes a margin problem. It models the downstream impact of connected decisions across assortment, pricing and inventory simultaneously. And agentic AI brings it all together — detecting the shift, showing where it impacts the plan, and presenting the best course of action to manage it.

The result is a planning process that moves faster and with greater confidence. Not because the data has changed, but because retailers can finally see all of it at once.

In a world where consumer trends are shifting faster than traditional planning cycles can absorb, a seasonal framework alone is no longer enough. The retailers who adapt will be those who build the infrastructure to see the complete picture and make decisions with confidence.
