The Frontline’s Cry: “What the Heck Is DX?”
“What the heck is DX?” — reports of SaaS fatigue among sales professionals are making headlines. The true nature of “SaaS fatigue,” where convenience actually exhausts the brain, is a hot topic. Voices from the field are piling up, saying they can’t keep up with multiple SaaS tools and that work is actually slowing down.
The core of this issue isn’t overusing tools or a lack of IT literacy. Rather, it’s a structural defect: management has never defined the purpose of IT. Why does the bigger picture get lost the more SaaS tools we add? Let’s think about this from a leadership perspective.
The Real Cause of SaaS Fatigue: “Fragmented Objective Functions”
The reason SaaS fatigue occurs is simple: each department introduces tools independently, and they never get integrated.
The sales team adopts Salesforce, marketing brings in HubSpot, and customer success installs Intercom. Each is a great tool on its own, but without proper integration, duplicate work arises—entering the same customer data into multiple systems.
We call this “fragmented objective functions.” IT’s purpose differs by department, and without overall optimization, tools just keep multiplying. Frontline staff constantly have to decide “which tool to use when,” draining their mental resources.
Why Sales Professionals’ Brains Get Exhausted
The real driver of SaaS fatigue isn’t operating the tools themselves—it’s the “switching cost” between them. One study reports an average of 60 app switches per day, with each switch requiring about 23 minutes to regain focus.
Consider a salesperson’s day: In the morning, check team updates on Slack, update yesterday’s deals in Salesforce, meet with a client on Zoom, summarize the meeting in Notion, and then submit expenses in Freee. That’s 5–6 tool switches in a single workflow.
This is what “brain fatigue” really means. The tools aren’t the problem—it’s the disconnect between them that raises cognitive load on the front line.
The Price of Management Failing to Define IT
The root cause of SaaS fatigue is that management has abandoned overall IT design. Tools are adopted “because they seem convenient” or “because competitors use them,” while integration planning is put off. This is the result.
Management needs to define these three things:
- What is the purpose of IT? (Revenue growth, operational efficiency, or risk management?)
- Which data should be centralized? (Customer data, inventory data, financial data?)
- What are the criteria for tool selection? (Cost priority, integration priority, or feature priority?)
If these aren’t defined and implementation is left to each department, tools optimized for individual silos will proliferate. The result is SaaS fatigue: “We have more tools, but work hasn’t decreased.”
Concrete Solution: Organize IT into Three Categories
To resolve SaaS fatigue, first categorize your company’s IT into three groups and clarify the purpose of each.
Business IT: Tools directly tied to revenue, like CRM and marketing automation. Prioritize speed of adoption and listen to the sales team’s voice.
Management IT: Tools for management decision-making, like BI tools and dashboards. Emphasize data centralization and integration.
Administrative IT: Tools for stable operations, like accounting software and attendance management. Focus on cost control and security.
Using this framework, take inventory of your current SaaS. Check if multiple tools overlap in the same category and whether they are properly integrated.
Management Decisions to Prevent SaaS Fatigue
So, what should management do concretely? First, set a “SaaS Cleanup Day” and list all company-wide SaaS contracts. Check for wasted licenses or overlapping features.
Next, consider an integrated platform. Many SaaS tools offer API integration, but designing those connections requires expertise. If you don’t have an internal IT team, hiring an external IT consultant is a viable option.
Case Study: A Small Business Cleans Up Its SaaS
Let me share a real example I was involved in. A manufacturing company with 50 employees had 11 different SaaS tools running wild. Sales used their own Excel spreadsheets, accounting had its own software, and production management was on a separate system—data was scattered everywhere.
First, we took inventory of all SaaS and eliminated functional overlaps. We made Google Workspace the central integration hub and connected each SaaS to it. As a result, monthly SaaS costs dropped by 30%, and the number of daily tool switches for sales staff decreased from 8 to 3.
SaaS Fatigue Is a Management Issue
“SaaS fatigue” is not a frontline IT literacy problem. It’s a structural problem caused by management failing to define IT’s purpose. Before adding more tools, management must decide why a tool is needed and which data should be integrated.
DX isn’t just about chasing convenience. True DX means reducing brain fatigue on the front line and creating an environment where people can focus on essential work. Business leaders, why not start reviewing your company’s SaaS environment today?
