Installation is the process of setting up the developed software application on the target hardware or production environment, configuring it properly, and ensuring it is fully operational for end-user access and use.
- The installation phase begins once the software has passed the necessary testing stages.
- This involves several technical and logistical steps to transition the system from the development or testing environment to the live, operational environment where it will be used regularly.
Key activities in this phase may include:
- Deploying the application code to servers or user devices.
- Installing required software components such as libraries, frameworks, or drivers.
- Setting up databases and configuring connections between software modules.
- Adjusting configuration settings (e.g., server addresses, security permissions, environment variables) to suit the client’s or organization’s infrastructure.
- Performing data migration if data needs to be transferred from an old system to the new one.
- Conducting a pilot run or soft launch to ensure everything is functioning before full-scale deployment.
There are also different installation strategies depending on risk, complexity, and organizational needs:
- Direct Cutover: Immediate switch from the old system to the new one.
- Parallel Installation: Running both old and new systems simultaneously for comparison.
- Phased Installation: Gradually implementing the system in stages or modules.
- Pilot Installation: Deploying the system to a limited group before a full rollout.
Importance:
A successful installation process minimizes downtime, reduces operational risks, and ensures that users can begin using the system effectively from day one. Proper planning and testing during this phase are critical to preventing post-deployment issues.
