If you use a version control system and regularly check your code in with that system, then you will easily be able to go back and check when you made certain changes to your code. Why is this useful?
Here are some situations where having this capability might be helpful. Have you ever ended up with a congested directory full of different versions of the same notebook or script?
This can make it hard to determine exactly which version of the code was used to produce a specific result. There are many reasons you might want to keep multiple copies of the same code around.
Here are just a few. Are you working on a project alongside other data scientists, analysts, or engineers? If you do not use a version control system then you might find yourselves in a situation where you have to trade off working one at a time to avoid tripping over half-baked changes that were added by your colleagues. With version control systems that support branching, you could easily work on separate versions of the same code then merge the changes back into one unified codebase later.

Why is version control important? In this section, we will touch on some of the major benefits of version control software. In the following sections we will go into more detail about situations in which these benefits can save you a lot of pain. Rolling back to previous versions. Your code is broken or has an elusive bug. This is one of the most compelling reasons for using version control software.
If you make updates to your code that break the code or introduce a bug that is difficult to find, you can easily roll back to a working version of your code. Then you can re-introduce your changes one at a time and test to make sure that the most recent change has not re-introduced the bug.
This is often much faster and easier than trying to back out where the bug is coming from in the fully modified code. You made code changes that are no longer necessary. Did you update your code to add a new feature to your model then realize that the new feature did not contribute much at all?
If you make changes to your code then your situation changes and you realize that those changes are no longer necessary, you can easily roll back to a previous version of the code with the help of version control software.
No need to manually undo all the changes you made to your code. Tracking when code changes. You notice a drop in model performance. Imagine this situation — you are looking at metrics on the performance of your model over time. The metrics might relate to the accuracy of the model, or perhaps the speed at which your model scores data.
You see a sudden drop in model performance starting on a certain date, but you are unable to remember what changes were made to the code on that date. If the performance degradation is significant, being able to track exactly which changes were added at the time the performance degradation began is invaluable.
A colleague asks you when code changes were made. A colleague stops by your desk or drops you an email and asks what date a key update was made to your data science model or data processing code.
Versioning also helps engineers merge changes to these documents before committing to specific drafts. Put simply, it takes the burden and worry of document management away from engineers, giving them more time to focus on the important aspects of their job.
For architectural, structural, mechanical, or electrical engineers, version control is a great tool for tracking and managing drawings, while for administrative users such as Accounts Payable and HR , it can be useful for managing submissions and transmittals as well as changes to key documents. Version control systems VCS are often stand-alone applications; however, in recent years, more features have been embedded into version control software, rendering classic version control systems obsolete.
Classic VCS can provide value for organizations; however, their features pale in comparison to the power and control provided by the features of document management systems like ImageSite or Engine-Box. The need for these features grows as companies continue to manage their documents electronically.
Some companies prefer to keep their documents within the system, while others prefer to print or download documents to their local device. Believe it or not, file tracking can be costly for engineers and administrative personnel. Rather than spending time and money handling documents, users can utilize a document management system to focus on completing the tasks assigned to them.
ImageSite is among the most robust document management systems on the market and includes all the functionality of a VCS and more.
