Law 19 — Know People: ប្រែប្រួលស្ទាយទំនាក់ទំនងតាម Client / Foreman / Supplier_ from Team Leadership with The 48 Laws of Power
Different roles care about different things. Adapt message, speed, and evidence to fit each person — you’ll reduce friction and win decisions faster.
🔑 Core Idea — ប្ដូរវិធីសាទូទៅឲ្យសមតួនាទី
English: People listen through their role: clients want clarity & risk control; foremen want resources & sequence; suppliers want volumes & cash flow. Tune your format and proof accordingly.
Khmer: មនុស្សស្តាប់តាមតួនាទី។ អតិថិជនចង់បានភាពច្បាស់ និងគ្រប់គ្រងហានិភ័យ; មេក្រុមត្រូវការធនធាន និងលំដាប់ការងារ; ក្រុមហ៊ុនផ្គត់ផ្គង់ចង់បានបរិមាណត្រឹមត្រូវ និងលំហូរប្រាក់។ កែប្លង់និយាយ និងភស្តុតាងឲ្យសម។
Principle: “Same facts, different frames.” — Keep facts constant, change framing per role.
🎯 Role–Style Matrix
| Role | What they value | Best format | Time window | Deal killers |
|---|---|---|---|---|
| Client (Owner) | Clarity, budget control, schedule risk, aesthetics | 1-page brief, options (A/B), visuals, cost & time deltas | Weekly summary, decision windows | Jargon, hidden risks, no options |
| Foreman (Site Lead) | Crew productivity, safety, sequence, clear handovers | Short SOP, checklists, drawings with highlights | Daily huddle, mid-shift updates | Late materials, vague specs, interruptions |
| Supplier | Reliable volumes, lead time, payment terms | PO with quantities, delivery slots, site access map | 48–72h notice for bulk; weekly consolidation | Last-minute changes, unpaid invoices, unclear drop point |
🤝 Client Playbook — អតិថិជន
Format & Rhythm
- Weekly Brief (1 page): Progress % → Risks → Decisions needed → Next week.
- Always offer Option A/B with cost/time deltas.
- Use visuals (before/after, 3D) instead of long text.
Scripts
- “We have 2 options: A saves 5 days (+$0), B adds 10% quality (+$350). Which matters more this week—time or finish?”
- “Risks: rain next 3 days → we propose reschedule of exterior paint.”
Tip: Clients hate surprises. Pre-commit to an update day/time.
👷 Foreman Playbook — មេក្រុម
Format & Rhythm
- Daily Huddle (≤10 min): Safety → Sequence → Constraints → Assignments.
- One-page SOP per task (steps, checks, “done” photo sample).
- Whiteboard for handovers (zone, time, quality points).
Scripts
- “Today’s critical path: rebar fix → formwork → pour 3PM. Sok, you own rebar QA; Nita, pour checklist.”
- “Blocker: missing 20mm rebar couplers. I’ll call supplier; shift sequence to prep beams.”
Tip: Keep radios clear: call signs + short codes reduce chaos.
🚚 Supplier Playbook — អ្នកផ្គត់ផ្គង់
Format & Rhythm
- Send PO with exact quantities, site map, and delivery window.
- Weekly consolidation message (what’s coming next week).
- Share unloading rules & contact on site.
Scripts
- “We confirm 120 bags cement, Wed 9–11am, Gate B. Contact: Nita (012…); crane on standby.”
- “If rain > 10mm, shift to Thu same slot — please hold stock.”
Tip: Fewer cancellations = better pricing over time. Protect the relationship.
🗣️ Universal Scripts — Role-based Frames
Client (EN / KH)
- “Here are two clear options with cost & time impacts. Which aligns with your priority this week?”
- “នេះជាជម្រើស ២ មានថ្លៃ។ ពេលវេលាផ្លាស់ប្តូរ។ តើអាទិភាពសម្រាប់សប្ដាហ៍នេះគឺអ្វី?”
Foreman
- “Critical path is X → Y → Z. Who owns each checkpoint? Call it back to me.”
- “Blocker? Say it now — we’ll resequence.”
Supplier
- “PO #0142: qty, window, drop point, site contact attached. Any constraint on your side?”
- “Payment plan unchanged; thank you for on-time slots.”

- Schedule variance shrinks; crew idle time ↓.
- Material stockouts rare; fewer urgent runs.
Simple Dashboard
| Metric | Target | Today | Note |
|---|---|---|---|
| Client decision time | ≤ 48h | 36h | Options A/B helped |
