Speed vs. Quality

When to decide fast, when to decide slow, and how to know the difference.

The Cost of Delay

Every decision has a delay cost. This is often invisible and underweighted.

Delay costs include:

• Opportunity cost (what you could be doing instead of deciding)
• Information decay (some decisions become less valuable over time)
• Mental burden (ongoing decision fatigue)
• Paralysis (avoiding action becomes the default)
• Lost optionality (options expire)

The insight: A good decision now often beats a perfect decision later.

The Two-Door Framework (Amazon)

Type 1: One-Way Doors

Irreversible or very costly to reverse.

Characteristics:

• High stakes
• Long-term consequences
• Difficult or impossible to undo
• Changing your mind is expensive

Examples:

• Having children
• Major surgery
• Selling a business
• Burning bridges

Approach:

• Gather extensive information
• Consult experts and experienced people
• Sleep on it (multiple times)
• Use formal decision frameworks
• Take your time

Type 2: Two-Way Doors

Reversible or low cost to reverse.

Characteristics:

• Can undo or change course
• Limited downside
• Fast feedback
• Learning opportunity

Examples:

• Most product features
• Trying a new tool
• Most hires (with probation)
• Testing a marketing approach

Approach:

• Decide quickly
• Bias toward action
• Learn from doing
• Iterate based on feedback

The Problem

Most decisions are Type 2, but people treat them like Type 1.

Result: Slow decisions on things that don't matter, wasted time, missed opportunities.

Information Value Curve

Information has diminishing returns.

           1   2   4   8   16  hours
                   Time Spent

Insight: You get most of the decision quality in the first 20% of time. The rest is marginal improvement.

The 40-70 Rule (Colin Powell)

Decide when you have 40-70% of the information.

• Less than 40%: You're guessing
• More than 70%: You're likely overthinking
• 40-70%: Use your judgment, decide, execute

Knowing When You Have Enough

Signs You're Overthinking

• You keep finding the same information
• New information isn't changing your view
• You're procrastinating disguised as "research"
• The same considerations keep circling
• Others who've decided are already learning

Signs You Need More Time

• You don't understand the basic tradeoffs
• You haven't talked to anyone with experience
• You're purely emotional (positive or negative)
• You couldn't explain your reasoning to someone else
• Critical information is obtainable with modest effort

Fast Decision Techniques

The 10-Minute Rule

Set a timer. Decide before it rings.

When to use: Low-stakes, reversible decisions that don't deserve more time.

The Coin Flip Method

Flip a coin. Not to let the coin decide, but to notice your reaction.

• Disappointed by the result? You wanted the other option.
• Relieved? The coin was right.
• Indifferent? Either option is fine, just pick one.

The "If You Had to Decide Right Now" Test

Remove time as a variable. What would you do if forced to decide immediately?

Often you already know the answer.

The Advisor Test

What would you tell a friend in this situation?

We often give better advice to others than to ourselves because we're not clouded by our own fears.

Slow Decision Techniques

The Waiting Period

Build mandatory delays into irreversible decisions.

• 24 hours for significant purchases
• 1 week for major commitments
• 1 month for life-changing decisions

The Devil's Advocate

Assign someone (or yourself) to argue against your preferred option.

What are the strongest arguments against?

The Multiple Perspectives Method

How would different people see this?

• How would a pessimist see this?
• How would an optimist see this?
• How would my mentor see this?
• How will I see this in 10 years?

The Pre-Mortem

Assume the decision failed. Why did it fail? Now prevent those failures.

Decision Velocity in Organizations

Why Organizations Decide Slowly

• Diffuse accountability
• Risk aversion (no one gets fired for not deciding)
• Too many stakeholders
• Lack of clear decision rights
• Meeting culture

Speed Up Organizational Decisions

1. Clear decision owner - One person decides
2. Time-box - Decision must be made by [date]
3. Disagree and commit - Once decided, everyone executes
4. Bias toward action - Default is to try, not to wait
5. Reduce stakeholders - Fewer people = faster decisions

The Optionality Principle

When uncertain, make decisions that preserve options.

Example:

• Learning a skill: Opens doors, doesn't close them
• Taking on debt: Closes options
• Developing relationships: Creates future options
• Over-specializing early: Reduces flexibility

Action: When speed vs. quality is unclear, ask "Which option preserves more future options?"

Common Speed Mistakes

Deciding Too Fast

Symptoms:

• Constant pivots and reversals
• Others feel whiplash
• Important factors missed
• Recklessness disguised as decisiveness

Solution:

• Distinguish true urgency from manufactured urgency
• Develop a quick checklist before deciding
• Build in minimal review for important decisions

Deciding Too Slow

Symptoms:

• Analysis paralysis
• Endless meetings
• Information gathering that never ends
• Opportunities expiring

Solution:

• Set deadlines
• Accept "good enough"
• Recognize diminishing returns
• Value learning from action

The Speed-Quality Checklist

Before deciding how to decide:

□ Is this reversible or irreversible?
□ What's the cost of delay?
□ What's the cost of being wrong?
□ Do I have 40-70% of the information?
□ Am I confusing uncertainty with lack of information?
□ What would I do if forced to decide now?
□ Am I overthinking a two-way door?
□ Am I rushing a one-way door?

Key Takeaways

1. Most decisions are reversible - Treat them that way
2. Delay has costs - Don't ignore them
3. Information has diminishing returns - 40-70% is often enough
4. Speed on small things, slow on big things - Match importance
5. Action generates information - Sometimes the best research is trying
6. Set deadlines - Decisions expand to fill available time
7. Commit after deciding - Second-guessing wastes energy
