Salesforce released an interesting feature around one year ago for tracking field work. If you haven’t heard about it and you want to see it in action, you can watch the a demo on youtube.
It has been getting updates and becoming more and more interesting.
If you wish you can take a look into the complete implementation guide, which contains all the information you need for activating Field Service Lightining in your Org.
There is also a managed package that contains several wonderful features that are not included in the activation that you can perform in your Org and are very useful, so I’d recommend to install it right away. You can find more details about this page on its own guide.
