1

Lead with Client Benefits, Not Your Features

Why it matters: Evaluators care about outcomes for their organization, not your capabilities list.

Weak Example

"Our company has 15 years of experience and uses cutting-edge technology including AI, machine learning, and cloud platforms."

Strong Example

"You'll reduce proposal response time by 85% while improving quality, allowing your team to bid on 4x more opportunities without adding headcount."

💡 What Makes It Better

The bad example lists features (years, tech stack). The good example quantifies client outcomes (85% time savings, 4x capacity).

🎯 How to Apply This Principle

  • Start every section with 'You will...' or 'This enables you to...'
  • Quantify benefits with specific numbers or percentages
  • Connect features to business outcomes (revenue, efficiency, risk reduction)
  • Ask: 'So what?' after every statement - if you can't answer with a benefit, revise
2

Use Active Voice, Not Passive

Why it matters: Active voice is stronger, clearer, and takes less space. Passive voice sounds bureaucratic and weak.

Weak Example

"The project will be managed by our certified PMP, and weekly status reports will be provided to stakeholders."

Strong Example

"Our certified PMP will manage the project and provide weekly status reports to stakeholders."

💡 What Makes It Better

Active voice identifies who does what. It's more direct and confident. 'We will deliver' beats 'will be delivered by us.'

🎯 How to Apply This Principle

  • Find 'will be,' 'was,' 'is,' 'are' - often signals passive voice
  • Put the actor (who) before the action (what): 'Team completes work' not 'Work is completed by team'
  • Use strong action verbs: deliver, achieve, create, manage
  • Exception: Use passive when actor is unknown or unimportant
3

Quantify Everything Possible

Why it matters: Numbers are credible and memorable. 'Significantly improved' is vague. '42% reduction' is proof.

Weak Example

"Our solution will significantly improve your team's efficiency and reduce costs while enhancing quality."

Strong Example

"Our solution will reduce proposal development time from 40 hours to 6 hours (85% savings), cut labor costs by $34,000 annually per writer, while increasing win rates from 15% to 23%."

💡 What Makes It Better

Specific numbers make claims credible. They also make your proposal memorable compared to vague competitor claims.

🎯 How to Apply This Principle

  • Time savings: X hours → Y hours (Z% reduction)
  • Cost impact: $X savings per year/project/user
  • Performance: X% improvement in [metric]
  • Capacity: X more [things] without adding resources
  • Quality: X% reduction in errors/issues
  • When you can't measure, use ranges: '15-20%' beats 'significant'
4

Write in Customer's Language, Not Jargon

Why it matters: Match the client's terminology. If their RFP says 'deliverable,' don't say 'artifact.' They're searching for their words.

Weak Example

"We'll implement an agile SDLC leveraging our proprietary DevSecOps pipeline to accelerate velocity."

Strong Example

"We'll use agile development with integrated security testing to deliver working software every 2 weeks."

💡 What Makes It Better

The bad example shows off vocabulary. The good example communicates clearly using simple language.

🎯 How to Apply This Principle

  • Read the RFP and note exact terms they use
  • Create a glossary: their term → your equivalent → use their term
  • Acronyms: spell out on first use, even if common in your industry
  • Test: Would a smart 12-year-old understand this sentence?
  • Government: match FAR terminology exactly

5

Show, Don't Tell

Why it matters: Anyone can claim 'excellent communication.' Proving it with an example is convincing.

Weak Example

"We have excellent communication skills and always keep clients informed throughout the project lifecycle."

Strong Example

"On our recent project with [Client], we provided daily 15-minute standups, weekly written status reports, and monthly executive briefings. When we identified a risk to the timeline, we notified the client within 2 hours with mitigation options."

💡 What Makes It Better

The good example provides specific evidence (daily standups, 2-hour response) instead of vague claims.

🎯 How to Apply This Principle

  • Replace adjectives (excellent, great, superior) with examples
  • Use mini-case studies: 'When X happened, we did Y, resulting in Z'
  • Include specific artifacts: 'dashboard,' 'report,' 'meeting'
  • Name the method: not 'good project management' but 'weekly steering committee meetings with documented action items'
6

Front-Load Important Information

Why it matters: Evaluators skim. Put your best stuff first - in every document, section, paragraph, and sentence.

Weak Example

"After conducting extensive research and consulting with industry experts, considering multiple approaches and methodologies, we determined that the optimal solution would be to implement a phased approach."

Strong Example

"We recommend a 3-phase implementation. After analyzing 5 approaches, this delivers fastest time-to-value while minimizing risk."

💡 What Makes It Better

Get to the point immediately. Background can come after you've stated your position.

🎯 How to Apply This Principle

  • Executive summary: lead with recommendation, not background
  • Paragraphs: topic sentence states the point, details follow
  • Bullets: most important item first
  • Invert pyramid: conclusion first, then supporting details
  • Ask: If evaluator reads only the first sentence, do they get the key point?
7

Use Specific Examples Over Generic Statements

Why it matters: Specific examples differentiate you from competitors making vague claims.

Weak Example

"Our team has extensive experience with similar projects across multiple industries and can handle complex requirements."

Strong Example

"Our team has delivered 12 federal RFP automation projects in the past 24 months, including a 3,000-user deployment at GSA and a classified system for DOD. Average implementation: 6 weeks from contract to production."

💡 What Makes It Better

The specific version (12 projects, GSA, DOD, 6 weeks) is memorable and verifiable. Generic could be anyone.

🎯 How to Apply This Principle

  • Replace 'extensive' with actual numbers: 'X years,' 'Y projects'
  • Name recognizable clients (with permission) or use 'Fortune 500 retailer'
  • Include timeframes: 'past 18 months' not 'recent years'
  • Specify technologies: 'React, Node.js, PostgreSQL' not 'modern tech stack'
  • Quantify results: '42% improvement' not 'significant improvement'
8

Address Requirements Explicitly

Why it matters: Don't make evaluators hunt for whether you meet requirements. State compliance clearly.

Weak Example

"Our approach incorporates best practices for security throughout the development lifecycle."

Strong Example

"Requirement 3.2.1: 'Contractor shall implement NIST 800-53 controls.' ✓ Compliant. We implement all NIST 800-53 Moderate baseline controls using our automated compliance framework, with quarterly audits by third-party assessors."

💡 What Makes It Better

The good version quotes the requirement number, states compliance, and explains how. Makes evaluator's job easy.

🎯 How to Apply This Principle

  • Use compliance matrix to track every 'shall' and 'must'
  • Start response: 'Requirement X.Y.Z: [quote exact text]'
  • State compliance: ✓ Compliant / ✓ Exceeds / ⚠ Exception (explain)
  • Explain HOW you meet it with specifics
  • For government: this is often difference between winning and losing

9

Write Tight - Cut Unnecessary Words

Why it matters: Page limits are real. Every word should add value. Concise writing is more persuasive.

Weak Example

"It is our belief that we have the ability to provide you with a solution that will help you to achieve your goals and objectives."

Strong Example

"We will help you achieve your goals."

💡 What Makes It Better

The bad version uses 27 words to say what 8 words communicate better. Padding wastes page limits.

🎯 How to Apply This Principle

  • Cut: 'in order to' → 'to', 'due to the fact that' → 'because'
  • Eliminate: 'It is,' 'There are,' 'We believe that'
  • Replace verb + noun with single verb: 'conduct an analysis' → 'analyze'
  • Remove redundancies: 'future plans' → 'plans', 'past experience' → 'experience'
  • Target: Cut 20-30% on second edit pass
10

Use Headers and Visual Hierarchy

Why it matters: Evaluators scan before reading. Clear structure helps them find evaluation criteria quickly.

Weak Example

"[Large paragraph discussing project approach, team qualifications, past performance, timeline, and deliverables all in one 300-word block]"

Strong Example

"Project Approach [150 words] Team Qualifications [150 words] Past Performance [150 words]"

💡 What Makes It Better

Breaking content into labeled sections with white space makes it skimmable and easier to score.

🎯 How to Apply This Principle

  • Use descriptive headers matching RFP evaluation criteria
  • Hierarchy: H1 for major sections, H2 for subsections, H3 for details
  • Keep paragraphs under 5-6 lines (more = readers skip)
  • Use bullets for lists of 3+ items
  • Add white space - dense pages intimidate evaluators
11

Prove Past Performance with Metrics

Why it matters: Past performance is usually 30-40% of evaluation score. Vague descriptions lose points.

Weak Example

"We successfully completed a large-scale implementation for a major client and they were very satisfied with our performance."

Strong Example

"Client: Federal Agency X | Contract: FA-2023-8832 | Value: $2.3M | Period: Jan 2023 - Dec 2024 Delivered enterprise proposal platform to 400 users. Reduced their proposal time from 35 hours to 8 hours (77% savings). Delivered 3 weeks early, under budget. CPARS: Exceptional rating (all categories)."

💡 What Makes It Better

The good version provides verifiable details, quantified outcomes, and official ratings.

🎯 How to Apply This Principle

  • Include: contract number, value, period, client name (if allowed)
  • Quantify outcomes: time savings, cost reduction, performance improvements
  • Mention: on-time delivery, budget performance, quality metrics
  • For government: include CPARS ratings if positive
  • Provide reference contact: name, title, phone, email
  • Format consistently across all past performance examples
12

Tailor Every Proposal - No Template Language

Why it matters: Evaluators spot copy-paste. Generic proposals signal you don't care about their specific needs.

Weak Example

"[Your company] is a leading provider of innovative solutions for organizations seeking to improve their business processes."

Strong Example

"The Department of Veterans Affairs' requirement for proposal automation directly aligns with our specialized experience. We've delivered 8 federal proposal systems, including 3 for VA medical centers in the past 18 months."

💡 What Makes It Better

The good version mentions specific client (VA), specific requirement, and directly relevant experience.

🎯 How to Apply This Principle

  • Use client's name 20-30 times throughout proposal
  • Reference their specific challenge from RFP background section
  • Match evaluation criteria language exactly
  • Cite their strategic plans or public statements
  • Never: 'Insert client name here' in final version (yes, this happens)
  • Custom executive summary for each proposal - never reuse

13

Handle Weaknesses Proactively

Why it matters: If you lack something, address it. Don't ignore it hoping evaluators won't notice - they will.

Weak Example

"[Say nothing about the fact that you don't meet the 'preferred 10 years experience' requirement]"

Strong Example

"While our company was founded 5 years ago (vs. preferred 10 years), our leadership team brings 45+ combined years of industry experience. Our past 3 government contracts (valued at $8M) demonstrate mature processes and proven performance."

💡 What Makes It Better

Acknowledging a gap with strong mitigation is better than letting evaluators dock points silently.

🎯 How to Apply This Principle

  • Identify 'preferred' vs 'required' - you must meet required
  • For gaps in preferred: acknowledge + provide compensating strength
  • Use 'While... our approach is...' structure
  • Emphasize what you DO have that's relevant
  • For serious gaps: consider teaming/partnering
  • Never: defensive or making excuses
14

Tell a Consistent Story

Why it matters: Your proposal should flow logically. Technical approach, past performance, and team should reinforce same themes.

Weak Example

"[Technical approach emphasizes agile speed, but past performance examples are all waterfall, and team has no agile certifications]"

Strong Example

"[Technical approach emphasizes agile. Past performance shows 5 agile projects. Team has 8 CSMs and PSMs. Management plan includes daily standups and 2-week sprints. Everything aligns.]"

💡 What Makes It Better

Inconsistencies make evaluators doubt your credibility. Coherent story is persuasive.

🎯 How to Apply This Principle

  • Choose 2-3 themes (speed, quality, innovation, etc.)
  • Reinforce themes in every section
  • Past performance should demonstrate themes
  • Team should have credentials supporting themes
  • Check: Do all sections support the same story?
  • Red flag: contradictions between sections
15

Use Callout Boxes for Key Points

Why it matters: Evaluators under time pressure appreciate visual cues for important information.

Weak Example

"[Key differentiator buried in middle of paragraph 3 on page 8]"

Strong Example

"[Callout box with icon] Why This Matters: We're the only bidder with existing FedRAMP authorization, saving you 6-9 months and $400K in compliance costs."

💡 What Makes It Better

Callout boxes make key selling points impossible to miss during rapid evaluation.

🎯 How to Apply This Principle

  • Use for: key differentiators, critical compliance points, risk mitigation
  • Limit to 2-3 per major section (overuse reduces impact)
  • Keep text short: 2-3 sentences max
  • Visual: border, background color, or icon
  • Check page limits: callout boxes can consume space
16

Write Executive Summary Last

Why it matters: It's the most important section - written first, it's speculation. Written last, it's synthesis.

Weak Example

"[Generic 2-page executive summary written before rest of proposal, not updated]"

Strong Example

"[1-page executive summary written after proposal is complete, pulling best elements: key differentiators, quantified benefits, compelling past performance, and explicit statement of compliance]"

💡 What Makes It Better

You don't know what your best arguments are until you've written the full proposal.

🎯 How to Apply This Principle

  • Write full proposal first (except exec summary)
  • Read through and highlight your 5 strongest points
  • Executive summary structure: Problem → Your Solution → Why You (3 differentiators) → Proven Results → Compliance
  • Keep to 1-2 pages max
  • Front-load: put your recommendation in first paragraph
  • Most evaluators read ONLY exec summary - make it standalone

17

Match RFP Structure Exactly

Why it matters: Evaluators have scoring sheets matching RFP sections. Don't make them hunt for where you addressed requirements.

Weak Example

"[RFP asks for: 1) Technical Approach 2) Management Plan 3) Past Performance. You organize as: 1) Our Company 2) Methodology 3) Team]"

Strong Example

"[Your proposal sections exactly match RFP: 1) Technical Approach 2) Management Plan 3) Past Performance]"

💡 What Makes It Better

Evaluators literally have a checklist matching RFP structure. Using different structure loses points.

🎯 How to Apply This Principle

  • Create outline directly from RFP table of contents
  • Use exact section numbers and titles from RFP
  • If RFP says 'Management Approach' don't call it 'Project Management'
  • Order sections exactly as RFP specifies
  • Include all required sections even if you think they overlap
  • For government: this is non-negotiable
18

Eliminate Marketing Fluff

Why it matters: Superlatives and puffery waste space and hurt credibility. Evaluators read hundreds of proposals.

Weak Example

"We are the industry-leading, award-winning, innovative provider of cutting-edge solutions, and we're passionate about delivering world-class results that exceed expectations."

Strong Example

"We've delivered 47 proposal automation systems with 94% client retention rate and average time savings of 82%."

💡 What Makes It Better

The bad version is all adjectives, zero proof. Good version is all facts, zero adjectives.

🎯 How to Apply This Principle

  • Delete: leading, best-in-class, world-class, cutting-edge, innovative, passionate
  • Replace adjectives with metrics: not 'fast' but '6-week delivery'
  • Replace superlatives with rankings: not 'largest' but '4th largest by revenue'
  • Show, don't tell: not 'excellent quality' but '99.7% defect-free rate'
  • Test: Remove every adjective - is sentence stronger? Often yes.
19

Use Graphics to Clarify, Not Decorate

Why it matters: Good graphics communicate complex information faster than text. Bad graphics waste space.

Weak Example

"[Stock photo of people shaking hands. Generic clip art. Decorative graphs with no data labels.]"

Strong Example

"[Org chart showing project team structure. Gantt chart showing actual timeline. Process flow diagram showing your methodology.]"

💡 What Makes It Better

Every graphic should communicate information that's hard to convey in text.

🎯 How to Apply This Principle

  • Ask: Does this graphic communicate information? If no, delete it
  • Label everything: axes, data points, phases, roles
  • Use: org charts, timelines, process flows, before/after comparisons
  • Don't use: stock photos (evaluators hate them), decorative elements
  • For government: may have page limits - graphics count as pages
  • Color: ensure it works in black & white (many print)
20

Proofread, Then Proofread Again

Why it matters: Typos signal carelessness. If you're careless in proposals, you'll be careless in delivery.

Weak Example

"[Proposal with client name spelled wrong, inconsistent formatting, 'their/there/they're' errors, wrong dates]"

Strong Example

"[Zero typos, consistent formatting, all dates/numbers match across sections]"

💡 What Makes It Better

A single typo can cost you the contract if it's in a critical area like the executive summary.

🎯 How to Apply This Principle

  • Read backwards (sentence by sentence) to catch typos
  • Search for previous client names from your templates
  • Check numbers consistency: team size, timeline, budget must match everywhere
  • Print and read on paper (catches different errors than screen)
  • Have someone who didn't write it proofread it
  • Check: date formats, company name spelling, title capitalization
  • Final check: Table of contents matches actual page numbers

21

End with Strong Call-to-Action

Why it matters: Even in formal proposals, you want to project confidence and prompt next steps.

Weak Example

"We appreciate your consideration of this proposal and hope to hear from you soon."

Strong Example

"We're ready to begin immediately upon contract award. Our proposed kickoff is within 5 business days of notice to proceed. Contact [Name] at [phone/email] to discuss any questions or schedule the project start."

💡 What Makes It Better

Confident close reinforces you're ready to execute. Weak close sounds uncertain.

🎯 How to Apply This Principle

  • Project confidence: 'We will deliver' not 'We hope to'
  • Specify next steps: timeline from award to kickoff
  • Provide clear contact: name, title, direct phone and email
  • Offer availability: 'Available for Q&A' or 'Can present to selection committee'
  • Thank them: brief, professional, not effusive
  • Final sentence: forward-looking ('We look forward to partnering') not passive ('Thank you for considering')
