Using alternate software I carry on learning English. I didn’t know what I have should write during a couple of weeks. And today I wrote some email to a company about using alternate software. Hello Colleagues, I prepared a table with a list of software of Microsoft this table in the attached Excel file. The list I separated of several parts. These parts are about user’s and server’s software. The table contains a column with a list of an alternate software. This software based on Open Source and for free. You have to understand that this software doesn’t look like software from Microsoft. Functions, features and etc. can be look differently than you used to. But in they used to use their environment and this situation will arise conflicts, stresses, and arguments in our office. The experience of use the laptop from the big meeting room shows when worker fall into another environment they get panic and stress. Besides alternate software in my opinion I tried to show an objectivity possibility to change an environment of several workers to alternative software. The most difficult changing will be change software of worker of next departments software developers, accounting, scanners. Also we have possibility to migrate from Microsoft Exchange. But you have to know that Exchange not only is email server. It is really difficult software has a lot of list of functions such as schedulers, meetings, reminders. Assistant our directors are used to using these functions. And if we want to use Open Source software we have to use more than one Exchange we have to use about six programs to replace it. This will make our system more difficult. Based on the above I added to table column called Saving. It shows how much money we can saving if we will get use alternate software. Best regards, Kirill.
