🚀 Executive Summary
TL;DR: Most tech projects fail not due to poor code execution, but because of flawed initial strategy or disastrous distribution (rollouts), often stemming from organizational silos. DevOps practices like mandatory pre-mortem meetings, embedding SREs early in the strategy phase, and implementing a ‘you ship it, you run it’ model are crucial to bridge these gaps and ensure robust, resilient deployments.
🎯 Key Takeaways
- Project failures frequently stem from flawed distribution strategies (e.g., un-indexed database calls causing self-DDoS) rather than poor code execution, highlighting the ‘silo of execution’ problem.
- Pre-mortem meetings, involving Dev, Ops, and Product, are crucial for proactively identifying distribution-related blind spots such as config map updates, API timeouts, and database migration locks before deployment.
- Embedding SREs from the strategy phase ensures early consideration of SLOs, error budgets, and blast radius, guiding development towards resilient, observable systems and preventing downstream distribution failures.
- The ‘you ship it, you run it’ model forces developers to adopt robust deployment practices, including canary releases, health checks, and idempotent migrations, by making them directly accountable for operational incidents.

It’s Not Your Code, It’s Your Rollout: A DevOps Take on Project Failure
I still remember the pager alarm blaring at 2:17 AM. It was for a “simple” feature launch—a new recommendation engine. The code was beautiful, passed every CI check, and ran flawlessly in staging. We were proud. But minutes after the production deploy, latency on our main checkout API shot up by 800%. Carts were timing out, sales were plummeting. The “perfectly executed” code was making thousands of tiny, un-indexed calls to our primary user database, `prod-db-01`, effectively DDoSing ourselves. We had a perfect *execution* of a completely broken *distribution* strategy. We focused so much on the ‘what’ that we never properly planned the ‘how’.
That night, I realized a truth that’s defined my career: We engineers love to obsess over execution. We’ll argue for hours about Go vs. Rust, Terraform vs. Pulumi, or the perfect microservice architecture. But I’ve rarely seen a major outage caused by a poorly written function. I’ve seen dozens caused by a brilliant feature released with zero thought for its impact on the surrounding ecosystem.
The Root Cause: The Silo of Execution
The problem stems from a cultural divide. The “strategy” people (Product, Upper Management) hand down requirements. The “execution” people (Developers) build the feature in a sterile, isolated environment. Then, they throw it over the wall to the “distribution” people (Ops, SRE, my team) to deploy and maintain. Each group thinks their part is the most important, but the real failure happens in the gaps between them.
When a project fails, it’s almost never because the developers couldn’t code. It’s because the initial strategy was based on a flawed assumption about the infrastructure, or the distribution plan was a fantasy that couldn’t survive first contact with the production environment. We focus on the middle piece of the puzzle and are shocked when it doesn’t fit.
Fixing the Disconnect: From Triage to Systemic Change
You can’t just tell people to “collaborate more.” You need to force the right conversations at the right time. Here are the three levels of intervention I’ve used, from a quick patch to a full cultural overhaul.
1. The Quick Fix: The Pre-Mortem Meeting
This is my go-to band-aid for teams who keep stumbling at the finish line. Before any significant release, you schedule a mandatory 30-minute meeting with Dev, Ops, and Product. The only agenda item is: “Assume this deployment has catastrophically failed. What happened?”
This isn’t about blaming people; it’s about identifying blind spots. You force the conversation away from “the code works” and toward the messy reality of distribution:
- “What happens if the config map doesn’t update on all pods in `auth-service-pod-xyz`?”
- “Does the new service have proper timeouts and retries for when the payment gateway API is slow?”
- “We’re adding three new database columns. Have we tested the migration script for locks on a replica of `prod-db-01`?”
It’s a “hacky” solution because it treats the symptom, not the cause. But it works. It forces a distribution-focused mindset right before it matters most.
2. The Permanent Fix: Embed Your SREs Early
The real, long-term fix is to break down the silos. Stop treating your Ops/SRE team like a gatekeeper at the end of the process. Embed them from day one—the strategy phase.
When an SRE is in the room while the Product Manager is whiteboarding, they ask different questions. They’re not thinking about button colors; they’re thinking about SLOs, error budgets, and blast radius. They see a “shiny new feature” and immediately start modeling its potential for failure.
| The Old Way (Siloed) | The New Way (Embedded) |
|---|---|
| Strategy: Product decides on a feature. | Strategy: Product and SRE co-define feature feasibility and SLOs. |
| Execution: Devs build the feature in isolation. | Execution: Devs build with SRE guidance on observability, resilience, and libraries. |
| Distribution: Devs hand off a container to Ops, who ask “What is this?” | Distribution: Ops/SRE have been planning the canary release and rollback strategy for weeks. |
Pro Tip: An SRE’s job isn’t to say “no.” It’s to ask “how?” How do we build this so it doesn’t wake me up at 3 AM? Getting that perspective in the strategy phase prevents entire categories of distribution failures.
3. The ‘Nuclear’ Option: You Ship It, You Run It
Sometimes, a team is just culturally unable to think beyond execution. They write the code, throw it over the wall, and wipe their hands clean, leaving Ops to clean up the mess. When all else fails, you implement the ultimate cure: the team that builds the service is now on call for it.
Nothing teaches a developer the importance of logging, monitoring, and safe deployment practices (distribution) faster than being the one whose phone rings when their “perfect” code breaks. Suddenly, things like idempotent database migrations and feature flags become non-negotiable.
Consider a team that ships a deployment script like this:
# deploy.sh - "Hope for the best" edition
kubectl apply -f new_feature.yaml
echo "Deployment successful!"
After one week of getting paged for failed rollouts, their script magically evolves to look more like this:
# deploy_v2.sh - "I don't want to get paged again" edition
echo "Running database migration in dry-run mode..."
./migrate --dry-run || { echo "Migration pre-check failed!"; exit 1; }
echo "Applying new deployment with a 10% canary..."
kubectl apply -f new_feature_canary.yaml
sleep 60 # Let it bake
echo "Checking canary health metrics..."
./check_metrics.sh || { echo "Canary is unhealthy! Rolling back."; kubectl apply -f old_feature.yaml; exit 1; }
echo "Canary looks good. Promoting to 100%."
kubectl apply -f new_feature.yaml
It’s a drastic measure, and it requires management buy-in, but it’s the single most effective way to force a team to own their strategy and distribution, not just their execution.
So next time a project is failing, look past the code. The bug probably isn’t in the IDE. It’s in the assumptions made during planning or the shortcuts taken during release. Fix the handoffs, and you’ll probably fix the project.
🤖 Frequently Asked Questions
âť“ Why do tech projects fail even when the code is perfect?
Tech projects often fail due to flawed initial strategy or disastrous distribution (rollout) plans, not typically because of poorly written code. The ‘silo of execution’ prevents holistic planning and consideration of the surrounding ecosystem’s impact.
âť“ How do these DevOps interventions compare to traditional project management approaches?
Traditional approaches often maintain silos between Product, Dev, and Ops, leading to ‘throwing features over the wall.’ DevOps interventions like pre-mortems, embedded SREs, and ‘you ship it, you run it’ actively break down these silos, fostering shared ownership and proactive risk mitigation across the entire software lifecycle, from strategy to distribution.
âť“ What is a common pitfall when trying to implement these solutions?
A common pitfall is attempting to ‘collaborate more’ without structured processes. The solution is to force specific conversations at critical junctures, such as mandatory pre-mortem meetings or embedding SREs directly into the strategy phase, to ensure distribution concerns are addressed proactively.
