It's not uncommon for many corporations with multiple locations or divisions to have different computer systems and networks that don't necessarily talk to each other. They may share a few common systems that allow them to communicate with other locations or business units to conduct business as usual. Since companies that are decentralized have systems, networks, and/or software that could differ from other locations, hiring managers will ask how you will gather information, who you will talk to, the method you will use to evaluate the new software, and how you will arrive at a decision to recommend or not recommend the software. Giving an example or short checklist of what you will cover in the evaluation process will be important.
