Heuristics

Practical first principles to improve systems, delivery, flow, reliability, and platform safety—drawn from real-world infrastructure and DevOps work.

29 heuristics

Heuristic

Increase Contrast, Not Volume

Prompt length does not guarantee novelty. Context contrast does.

ArchitectureOperations

Heuristic

Your Deployment System Is a Product

Great deploys are built, not improvised.

AutomationDelivery

Heuristic

You Cannot Rely on People Under Stress

Design for tired humans.

ReliabilityOperationsSRE

Heuristic

You Build It, You Run It

Build it, run it.

CollaborationOperationsSRE

Heuristic

Work in Small Batches

Small batches make failure cheap and learning fast.

FlowAutomationDelivery

Heuristic

Use Simple Solutions Until They Hurt

Complexity should be earned.

Architecture

Heuristic

Trust Is Earned, Not Assumed

Trust must be proven.

SecuritySecurity

Heuristic

The Best Configuration Is No Configuration

Defaults beat decisions.

AutomationArchitectureDelivery

Heuristic

Test Where It Breaks, Not Where It Works

Test the breaks, not the breeze.

AutomationReliabilityDelivery

Heuristic

State Is Your Enemy, Treat It Carefully

Less state, fewer surprises.

Heuristic

Standardize Before You Optimize

Standardize, then optimize.

Flow

Heuristic

Short Feedback Loops

Fast feedback beats perfect plans.

FlowLearning

Heuristic

Shift Security Left

SecurityReliabilitySecurity

Heuristic

Shared Responsibility, Shared Success

Shared goals create shared wins.

Collaboration

Heuristic

Heuristic

Make Infrastructure Disposable

Cattle, not pets.

AutomationReliabilityInfrastructure

Heuristic

Limit Work in Progress

WIP is invisible debt on your flow.

Flow

Heuristic

Know What You Have

Inventory before security.

SecuritySecurity

Heuristic

If You Cannot Automate It, You Do Not Understand It

Automate to learn, not just to save time.

AutomationArchitecture

Heuristic

Fail Closed, Log Everything, Recover Gracefully

Safe failure beats quiet failure.

Heuristic

Every Output Is Someone Else's Input

Handoff quality sets the pace of flow.

Heuristic

Empower Autonomous Teams

Autonomy with guardrails.

CollaborationFlow

Heuristic

Continuous Learning Culture

Learning is uptime.

Heuristic

Blame the Process, Not People

Fix the system.

LearningReliability

Heuristic

Avoid Local Optimization

Optimize the system, not the silo.

Flow

Heuristic

Automate What You Repeat

Repeatable work belongs to code.

AutomationFlow

Heuristic

Optimize for Flow, Not Silos

If downstream is blocked, upstream speed is just inventory.
