Make Checklist: 8 Things Before Going Live
I’ve seen 3 production agent deployments fail this month. All 3 made the same 5 mistakes. If you’re about to launch a new application or service, you need a solid plan. Here’s a make checklist that can save your sanity and your reputation.
1. Code Review
Why it matters: A thorough code review helps catch bugs and ensures the code meets the team’s standards. Ignoring this step can lead to production issues and performance bottlenecks.
# Sample code review checklist
def review_code(code):
assert code is not None, "Code can't be None"
# Add more checks as necessary
What happens if you skip it: Skipping code review can lead to bugs in production that might cost you customers and damage your brand image. Trust me, I’ve seen projects go down in flames because of overlooked errors.
2. Automated Testing
Why it matters: Automated tests save you time and effort by checking your code for defects. They help ensure that new changes don’t break existing functionality.
# Sample automated test using unittest
import unittest
class TestMyFunction(unittest.TestCase):
def test_example(self):
self.assertEqual(my_function(1, 2), 3)
if __name__ == '__main__':
unittest.main()
What happens if you skip it: Failing to implement automated tests is like going into battle without armor. Your application might work in staging but crash in production, leading to user frustration and potential financial loss.
3. Load Testing
Why it matters: Load testing identifies how your system behaves under heavy traffic, helping ensure it can handle real-world usage. This is a must-do if you expect your application to grow.
# Sample command to run a load test using Apache JMeter
jmeter -n -t test_plan.jmx -l results.jtl
What happens if you skip it: Not load testing your application can result in downtime when it suddenly gets more traffic than expected. Remember, most users won’t come back after a bad experience.
4. Environment Configuration
Why it matters: Proper configuration of environments (development, staging, production) ensures consistency and reduces the risk of deployment failures. Misconfigurations can lead to data loss or functionality issues.
# Sample environment variables setup in .env file
DATABASE_URL=postgres://user:password@localhost:5432/mydb
API_KEY=your_api_key_here
What happens if you skip it: If you neglect environment configuration, you may end up with a working app in development that crashes in production due to misaligned environment variables. I’ve been there—it’s embarrassing.
5. Security Checks
Why it matters: Security vulnerabilities can lead to data breaches and loss of trust from your users. A security audit before going live helps to identify and mitigate risks.
# Sample command to scan for vulnerabilities using npm audit
npm audit
What happens if you skip it: Ignoring security can lead to a breach that not only affects your users but can also land you in legal trouble. Better safe than sorry.
6. Backup Plan
Why it matters: Having a backup plan ensures that you can quickly recover from unexpected failures. This reduces downtime and minimizes data loss.
# Sample command to backup a PostgreSQL database
pg_dump mydb > mydb_backup.sql
What happens if you skip it: Without a backup plan, you risk losing everything if something goes wrong—imagine waking up to a deleted production database. Not fun.
7. Monitoring Setup
Why it matters: Monitoring your application post-launch helps quickly identify issues and performance bottlenecks. This allows you to react promptly before it impacts users.
# Sample command to set up monitoring with Prometheus
# Prometheus config example
scrape_configs:
- job_name: 'my_app'
static_configs:
- targets: ['localhost:9090']
What happens if you skip it: Failing to set up monitoring means you won’t know about issues until users start complaining. Proactive monitoring saves your reputation.
8. Documentation
Why it matters: Good documentation helps your team and users understand how to use and maintain the application. It can speed up onboarding and reduce the number of support requests.
# Sample README structure
# Project Title
## Installation
1. Clone the repo
2. Run `npm install`
## Usage
Run `npm start` to start the app.
What happens if you skip it: Lack of documentation can lead to confusion, mistakes, and longer onboarding times for new team members. I’ve seen teams struggle because the documentation was non-existent.

The One Thing
If you only do one thing from this checklist, make sure to implement automated testing. This step ensures that your code behaves as expected, which is critical for maintaining quality as your application grows. Trust me, missed tests can lead to endless headaches down the line.
FAQ
- What is the most common mistake before going live? Not performing adequate testing is often the top reason for post-launch failures.
- How long should a check take? Ideally, you should allocate a few days to a week for these checks, depending on the size and complexity of your application.
- Can I skip load testing? If you expect high traffic, don’t skip load testing—it’s critical to ensure your app can handle the load.
- How often should I update my documentation? Whenever there’s a significant change in your codebase or processes, your documentation should be updated accordingly.
- Is a backup plan necessary? Absolutely. It’s not just a nice-to-have; it’s essential for disaster recovery.
