When talking about usability every business needs a system that will not only cover their basic needs but will also accommodate any advancements that may occur with time. Another aspect that is of great importance within ERP solutions is the level of integration of the system. ERP systems need to work well with other applications either for internal business needs or when dealing with outside entities with which data needs to be exchanged. 

As expected from Microsoft, they have made sure that Dynamics 365 works with all their other products making it the perfect example of a hyper-connected software. Due to this, businesses can take full advantage of the functionalities that the Office 365 suite offers without worrying if this system will integrate with their ERP system. This has also been the case with the systems evolution in the Market. Even though new functionalities are continuously being added to D365 these new functionalities are designed to work effectively with all other Microsoft products. Additionally, Dynamics 365 software has a look and feel that is very similar to other Microsoft software like Office.  These features provide a sense of familiarity to most users which in turn accelerates the user training process and increases the effectiveness of the implementation process. The system also offers a high level of integration with Microsoft products which gives the users the ability to perform several tasks in the ERP system like create Word documents or even create e-mails within the systems interface.

On the other hand, even though SAP ERP is considered by many an antiquated system it has been progressively updated through continuous iterations over the years.  This subsequently brings several concerns when companies need/want to upgrade to the latest version of the software. These upgrades will force the company to invest in an implementation project that will roughly have the same cost as the initial implementation of the system due to the integration of outside software (such as Office).  Many times, these integrations are affected, and this will further increase the expense of the implementation since additional hours will be needed to solve these issues. In regard to the usability the system can be a very powerful tool, but the navigation is not as intuitive as the D365 platform. On top of this, many businesses have often complained that the standard SAP solutions can be too restricted and cause businesses to have to redesign their processes when switching to this ERP platform.
