Cutting 70% of Custom Systems: Why He Became the Company’s Most “Anti-System” Person
“The person who understands systems best is now dismantling them—by hand.”
When Lin Yuan signed off on scrapping 70% of the company’s custom-built IT applications, the internal ripple was no less than a minor earthquake.
As CTO of a tech company, Lin Yuan had long been an unwavering believer in “heavyweight architecture.” Over the past five years, he’d led three major IT overhauls, always striving to weave an impenetrable web of code—from the underlying data platform to front-end approval workflows. He wanted every business action to snap precisely into place along pre-defined tracks.
Yet today, this former “system fanatic” has become the company’s most “anti-system” person.
He slashed away at costly, maintenance-heavy custom applications—and moved the entire team’s day-to-day collaboration onto Feishu. No complex second-layer development. No diving deep into labyrinthine configuration backends. Instead, he rebuilt the business’s foundational structure using only Feishu’s most basic capabilities: instant messaging, Docs, Multi-dimensional Tables, Calendar, and video conferencing.
This sharp U-turn—from “worshipping scale” to “returning to minimalism”—was no impulsive decision.
After countless late-night bug hunts and watching business units miss critical opportunities due to rigid processes, Lin Yuan began questioning a fundamental problem:
Why do increasingly complex systems actually hinder real organizational efficiency?
When tools multiply into isolated data silos, and “adapting to business needs” devolves into “cutting feet to fit shoes,” are we truly empowering organizations with systems—or imprisoning innovation within them? This isn’t just Lin Yuan’s personal dilemma; it’s a quiet, pervasive pain point across the entire enterprise digital transformation journey.
Deconstructing “System Worship”: Why Tool Stacking Fails in Real Business
Over the past few years, corporate digitalization has fallen into a kind of “pile-it-on-and-miracles-will-happen” delusion.
Many managers cling to a belief: the bigger the system, the more modules it contains, the tighter its workflows—efficiency will inevitably follow. They eagerly build heavyweight IT architectures, attempting to cover every possible business scenario through exhaustive enumeration.
But frontline battles are never fought according to script.
The moment market winds shift, frontline teams need rapid fire support—not ten interlocking approval forms to fill out before charging forward.
This “system worship” collapses quickly when confronted with reality. Fragmented information flows and rigid handoff points turn massive architectures into data silos and process shackles.
A salesperson secures a deal in an instant message—then must switch to another system to enter the contract. Product and R&D teams align on requirements in a Doc—only to jump to a third tool to submit code reviews. Tools multiply endlessly, yet data repeatedly breaks mid-transit across departmental walls.
The higher the stack of tools, the slower the organization’s “adaptability” becomes.
Systems should extend our limbs—helping enterprises explore unknown territories swiftly. But under the obsession with “bigger and more comprehensive,” they instead become heavy armor that restricts movement.
Breaking free from this delusion doesn’t mean reverting to stone-age practices—it means returning collaboration to common sense.
When Lin Yuan decided to cut away those flashy but hollow custom modules, what he was truly seeking wasn’t an all-encompassing “mega-system.” Instead, he sought a foundational capability flexible enough to expand and contract alongside the business itself. That demands tools capable of stepping out of their pre-set process greenhouses—and learning, once again, how to adapt in unfamiliar tasks and open environments.
Rebuilding “Adaptability”: Returning Collaboration Tools to Common Sense and Context
True agility isn’t achieved by endlessly layering on custom modules—it comes from having a solid foundation that lets you freely assemble pieces for unfamiliar tasks.
Building collaboration tools requires more than architectural “extensibility.” It demands resilience against the unpredictability of real-world business. Feishu delivers exactly that agile foundation—instant messaging, Multi-dimensional Tables, Docs, Calendar, video conferencing, and approvals. These seemingly ordinary, common-sense capabilities form the “LEGO bricks” of enterprise digitalization.
Here, tools shed their rigid process shells and become intuitive extensions of how people naturally work.
Right after wrapping up a cross-departmental video meeting, participants don’t need to switch windows—they simply jot down conclusions and action items in the shared Doc. When requirements change, project managers drag and drop data cards in Multi-dimensional Tables to track progress. A new approval? Just initiated with a tap, right inside an instant messaging conversation.
No jarring system jumps—just seamless, contextual flow of information.
Calendar entries, Doc-based consensus, and chat-driven decisions, once tightly interlocked, bring the organization’s “adaptability” to life—through these small, everyday actions. They transform previously rigid management routines into organic, breathing entities that stretch and contract with the business.
More importantly, when these robust, uncluttered, common-sense foundations meet the AI wave now permeating every corner of the workplace, a far more imaginative leverage effect begins to take shape. The more restrained the foundational capabilities, the smoother the integration of third-party intelligent work agents. Once the underlying tools are ready to host higher-order intelligence, the leverage of an open ecosystem is only just beginning to reveal its power.
The Leverage of an Open Ecosystem: Seamless Integration of Third-Party Intelligent Work Agents
AI’s full-scale infiltration into workplace scenarios is now inevitable—but what enterprises truly need is not a closed “AI black box.”
Intelligence shouldn’t be an island—it should be flowing water.
Feishu’s open ecosystem provides precisely the riverbed for that water to flow. Rather than monopolizing all intelligent capabilities, Feishu enables various third-party intelligent work agents and AI-powered office tools to integrate naturally into existing workflows.
This integration happens in the most authentic, granular business contexts.
While drafting a Feishu Doc, employees summon a third-party AI assistant with one click—to refine wording or spark ideas mid-document. Facing dense operational details in a Multi-dimensional Table, they pair it with specialized AI tools to clean, analyze, and extract insights.
No hopping between fragmented browser tabs. No cumbersome system switches. Intelligent tools are no longer detached “add-ons” operating outside core work—they may appear as a comment in a Doc, or a calculated field inside a table.
The logic behind this is refreshingly simple: enable interoperability, encourage complementary use. Feishu steps back—solidifying connections among its common-sense capabilities (instant messaging, Docs, Multi-dimensional Tables, Calendar)—and returns the choice of cutting-edge AI to frontline business teams. It offers fertile soil, letting everything grow organically within a unified collaborative context.
When tools cease to function as rigid control levers—and instead become on-demand digital co-pilots—a deeper, more profound shift unfolds. It quietly reshapes the relationship between people and systems—and propels organizational management paradigms toward their next leap: from mechanical “process control” to genuine “intelligence activation.”
An Evolution in Organizational Paradigms: From “Process Control” to “Intelligence Activation”
The ultimate goal of digitalization isn’t to discipline people with cold, impersonal systems—but to empower them with tools that feel like natural extensions of themselves.
Looking back at Lin Yuan’s team’s journey—slashing 70% of bloated custom systems and returning to a common-sense collaboration foundation—this wasn’t merely a technical architecture slim-down. It was a cultural transfusion for the organization.
Information no longer bounces off departmental walls. Individual creativity flourishes within a shared context. And the very nature of collaboration transforms: it ceases to be top-down process control—and becomes bottom-up intelligence activation.
Where does next-generation intelligent collaboration live?
Not in lengthy feature lists. Not behind walled-off system gates. It lives where common-sense tools intersect with open ecosystems. It lives in the balance between procedural rigor and agile responsiveness. It lives at the intersection of system foundations and individual creativity.
Feishu lays down a solid digital foundation using common-sense capabilities—instant messaging, Docs, Multi-dimensional Tables, Calendar, video conferencing, and approvals. The seamless integration of third-party intelligent work agents then allows this foundation to sprout lush, adaptable branches—capable of thriving across countless business scenarios.
Tools step back. People step forward.
When enterprises stop worshipping the myth of “bigger and more comprehensive” systems—and instead embrace the philosophy of “agile adaptation” within an open ecosystem—true organizational intelligence will naturally break through the soil.
