When systems engineers build or repair computer software or hardware, they need consistent processes in place to keep it running smoothly. Configuration management is the name for this set of processes, ensuring that machines and applications perform steadily over their lifespan. Thankfully, configuration management doesn’t all have to be done by hand. Configuration management tools and software can automate some of the manual tasks to streamline procedures and improve operational efficiency.
What is Configuration Management and Why is It Important?
Configuration management is the set of processes that systems engineers use to create consistency when they’re building or repairing hardware and software. It tracks changes and helps keep systems more stable over their lifetimes, even when the systems are complex or granular. Configuration management may track metadata, including:
Configuration management creates a single source of truth for this information, improving organization and minimizing downtime.

What is a Configuration Management Tool?
A configuration management tool is a type of software that manages and tracks the changes that happen during configuration management. It can also automate some of the change and deployment procedures, carrying them out faster and with less potential for human error. Configuration management tools track resource usage, prevent duplicate work, and identify where problems are coming from within the system.
Benefits of Software Configuration Management Tools
Software configuration management tools lower the likelihood of human error, make systems more scalable, and reduce the volatility of software systems.

Fewer Human Errors
Because configuration management tools can automate tasks during systems engineering, they lower the likelihood that human error will occur. It also tracks changes in the software, meaning it’s easy for organizations to roll back to an earlier version if someone does make a mistake or the system malfunctions.
Employers are struggling to fill their technology roles, meaning they can’t rely on more personnel in order to scale their systems. Instead, configuration management tools can improve an organization’s operational efficiency, allowing it to create more scalable systems without enlarging its staff. Configuration management also prevents unnecessary duplication, so tasks can get done faster.

More Stable Software & Hardware
Configuration management provides a defined set of processes, meaning developers and IT staff should be handling the same tasks in the same way each time they perform them. It can also help teams identify and solve problems faster due to the detailed audit trails. Stable software and hardware results in less downtime and fewer unplanned resource expenditures.
Top Configuration Management Tools
The best configuration management tools should make it easy to track software changes and enforce organizational policies. Businesses looking for configuration management tools should consider the following platforms, chosen for their high user ratings and the features they offer.
