1.2.2.4. 💡 First Principle: Establish a Plan and Implement the Solution

💡 First Principle: A clear plan of action, developed after the cause is known, ensures that the repair is performed correctly, efficiently, and with minimal risk of creating new problems.

Scenario: You have determined that a user's slow computer is caused by a failing mechanical hard drive (HDD). Your plan of action is: 1) Inform the user and get approval for the replacement. 2) Schedule the repair. 3) Back up the user's data. 4) Obtain a new solid-state drive (SSD). 5) Clone the old drive to the new SSD. 6) Install the SSD and verify the system boots.

Once the cause is determined, you need a plan to fix it. This isn't just about the technical steps but also about considering the impact on the user and the business.

Key Actions:

• Develop a Step-by-Step Plan: Outline the exact steps needed to implement the solution.
• Consider Potential Impacts: Will this fix require downtime? Does the user need to be notified? Are there any security implications?
• Obtain Necessary Permissions: If the fix involves significant changes (e.g., replacing a server component, making a network-wide change), ensure you have approval.
• Implement the Solution: Follow your plan carefully to resolve the issue.

⚠️ Common Pitfall: Rushing into a fix without a plan. This can lead to forgotten steps, such as failing to back up data before replacing a hard drive, which can turn a small problem into a disaster.

Key Trade-Offs:

• Quick Fix vs. Permanent Solution: Sometimes a temporary workaround is needed to get a user operational quickly, but it must be followed up with a permanent solution to prevent recurrence.

Reflection Question: When planning to replace a critical component like a power supply, what non-technical steps (like user communication and scheduling) are just as important as the technical steps?
