A couple days ago, typhoon Haiyan caused severe damage to Philippines, and many people lost their life and/or their families. Over the last decade, many natural disasters have occurred worldwide. Today, most companies rely on management information system. Natural disasters often severely damage MIS and cause system to shut down. Companies normally face two issues: the high cost for fixing and re-starting MIS, and the loss of important business data, such as customer information and order history. How should a company solve these issues? I have several recommendations. Firstly, a company should buy disaster insurance for its MIS if the company is located in a place where natural disasters regularly occur. Secondly, companies should back up their MIS data regularly to reduce the risk of losing data. Thirdly, if financially affordable, company should build an emergency system, so that MIS can be quickly brought online. Finally, countries should have the ability to forecast disasters. Therefore, companies can shut down their MIS in advance and try to save their machines and data.
