Customer Relationship Management
What is CRM?
- Customer and deal information in one place
- Context carries over when owners change
- The foundation for pipeline and nurturing
The first thing that changes after adopting a CRM is the scene at the weekly sales meeting. Before, the team lead asked, "What happened with that deal?" and the rep tried to recall the answer from memory. Now the same screen is up on the wall, and the question is "why has this been stuck at the proposal stage for three weeks?" Sales shifts from work that relied on personal notebooks and memory to shared work anyone can open. Whether the rep goes on vacation or leaves the company, the next person reads the last call notes before picking up the phone. This is the point where ownership of the relationship passes from the individual to the company.
In practice, it helps to sort CRM into three types: operational (SFA-style), which runs sales activities and the pipeline; analytical, which produces stage-by-stage conversion rates and sales forecasts; and collaborative, which ties in consultation and after-sales service history. You also need clear boundaries with neighboring tools. Marketing automation (MA) warms up prospects before sales gets involved, CRM is where an assigned sales rep closes the deal, and ERP handles post-contract order fulfillment, production, and settlement. That is why many companies first set a handoff rule: only leads that pass a set score in MA move into CRM as 'opportunities'.
Success or failure in design often comes down to the number of input fields. If you make fifteen fields required, no one fills them in, so it is better to start with four or five: client, amount, expected close date, and next action. Don’t copy another company’s stages, either. Set just 4–6 that follow your own sales flow, and define the condition for moving past each stage as a verifiable fact, such as “quote sent” or “meeting with the approving executive held”.
The most common problem in practice is team members seeing the CRM not as a management tool but as a surveillance tool. They then log only the deals that went well and quietly neglect the ones that fell through, or, to avoid pressure over results, park hopeless deals in the negotiation stage. Run a forecast on a pipeline inflated this way and expected revenue comes out at twice the real figure. A company that hires staff or stocks inventory ahead based on that number takes the loss at quarter-end. Management holding the line first that “entries are handover material, not evaluation material” matters far more than which tool you choose.

Consider a hypothetical case. Company A makes industrial valves, with 80 employees and annual revenue of about KRW 22 billion (≈ US$16,459,700). Its seven sales reps each tracked accounts in their own Excel files and notebooks. When a ten-year assistant manager left, follow-up talks with the three accounts he handled stopped completely. Quarterly sales forecasts were also off by more than 30% every time, which even threw production planning into disarray.
- The head of sales announced, "Collecting Excel files ends this month," picked out only the 62 live deals, and moved them into the CRM over two weeks.
- The sales team lead cut the stages to four (consultation, proposal, negotiation, and contract) and defined the conditions for moving on as observable facts, such as "if a quote has been sent, it's a proposal; if you've met the approving executive, it's a negotiation."
- Required input was limited to four fields: client, amount, expected close date, and next action. The team made a three-line note right after each call a rule, and the weekly meeting did not discuss any deal that was not in the CRM.
- When the next-action date passed, the owner got a notification. Any opportunity stalled for more than 14 days showed up in red on the division head’s dashboard, so the team decided on the spot whether to save it or drop it.
- Six months later, the quarterly revenue forecast error fell from 32% to 9%, handover time for departing employees dropped from two weeks to three days, and deals left to stall at the proposal stage were cut in half, lifting the win rate from 18% to 24%.
