The analysis note Hello. I carry on to analyze the situation about how we use software of Microsoft in our company and today I wrote analysis note to our company management. It’s a boring and difficult text. I hope I didn’t make a lot of errors. Coworkers good afternoon, In connection with our company loses the partner status of Microsoft company and our company loses right to use some software of Microsoft. Department Information Technologies made an analysis of the situation, defined and calculated software of Microsoft licenses which our company has to buy. There is the table in the annex 1. The table has 3 parts. First. It’s an existing situation. It shows software of Microsoft which our company uses now. The Company has to buy these products to obey the law. It is most expensive and easiest way. It envisages to buy all licenses of products which the company uses without extra works. Second. It’s an optimizing case. It shows how we can change using some products to simpler products. The simpler products have less functions but they aren’t business critical but their price substantially less. In my opinion this case more balanced, because it doesn’t break usual environment of workers and its direct cost significantly less, but it has the minuses. The company management should take into account these minuses: A) IT specialists of company have to reinstall some products of Microsoft on a few servers. It can take a month. B) Also, IT specialists have to reinstall the operating systems and other software on all computers of workers. It can last about couple months. Third. It is a mixing case. It shows that the company can change some products of Microsoft to alternate software. Alternate software basically means Open Source software. This case is less expensive and more difficult because it makes more difficult environment for workers and IT specialists. The company has to change office package to open source office package also a few computers of the workers have to change their Windows to Linux. It will be very difficult time until they will be used to. It can last months. Also should take into account that company has to change one comprehensive solution of exchange emails and collective work to five different. It makes more complex work for support the park of the servers for IT specialists of the company and it require to hire more IT specialists.
