IT Job Roles and Responsibilities
1. Project Manager
A project manager, in this case, is someone that plays a managerial role in a company’s project. In fact, this is one of the most important IT job roles. The manager is responsible for his or her team. He or she makes sure that deadlines are met, and the project proceeds as planned. It mainly includes planning, design, initiation, monitoring, execution, and control.
2. IT Director
In most cases, the term director is associated with big positions in a company, and is often associated with a board role. As one of the top IT job roles, the IT director is responsible for planning, managing and executing the core-infrastructure of a company. The primary role of the IT director is to oversee all the technology operations within the firm. The director then evaluates what his or her team does to make sure that the activities are in line with firm’s main objectives. On top of that, the IT director makes sure that all departments have their technology needs met by his or her team.
3. IT Manager
The rank of an IT manager is definitely lower than that of a director, however, the role is still very crucial for any IT department. Every IT department has staff members that are meant to deliver results at the end of the day. The IT manager supervises most of the workers in the IT department. He or she is in charge of motivating them and making sure that they do what they are supposed to do. The IT manager’s roles include monitoring, planning, coaching, disciplining employees, and counseling.
4. Software Engineer
This position can also be referred to as a software architect, system engineer or application programmer. The main work typically involves creating and programming system-level software such as database systems, operating systems, and embedded systems. Their primary role is to ensure that they understand how both software and hardware work and to use them appropriately. However, the responsibilities don’t stop there. The software engineer is also required to interact with both colleagues and clients to explain which system or solution is going to be more suitable for use.
5. Systems Analyst
A systems analyst can also be called a solutions specialist, product specialist or a systems engineer. Their primary work mainly involves identifying, analyzing, and coming up with new information systems that will provide a viable solution. This is mostly done as a response to the requests of customers or just for the business. They also have to make sure that they determine the costs and total time required to bring the information systems into effect.
6. Helpdesk Support
There are times when your team could encounter system problems. Perhaps, a piece of hardware or software has malfunctioned. You need helpdesk support to deal with such issues. This is a professional that knows about common computer problems. Without them, business operations could stall because an employee can be stranded, and there’s no one to help.
7. Network Designer
As much as helpdesk support can solve most IT problems, there are other issues that they can’t solve. You may experience system shutdowns or slow internet. In that case, you need an expert in maintaining communication systems. These professionals will also be responsible for setting up cyber security systems for the organization.
IT involves many job roles and responsibilities that all work hand-in-hand to deliver results. As you begin your business, you should know about these roles so that you can know which ones are going to be the most suitable for your firm.
Sage wisdom states that there are two sides to every coin. This timeless wisdom will be borne out in spades with Windows 8/RT. Let's get into the dark side first.
If your users are veterans of Windows it is safe bet they are going to take one look at Windows 8 and scream blasphemy. Users whose brains are geared towards visual learning will undoubtedly yell the loudest and longest.
There's a good reason for this. Mick Jagger brought his band to the Redmond campus, performing live "Start Me Up" in the summer of 1995 (it was a great show). This heralded in the abandonment of program icons sitting on the desktop and introduced the now legacy Start button.
Ending the life of the 17-year-old start button is not going to go well with some users.
F#, which is usually pronounced as F sharp is one of the newly launched and rapidly developing programming languages. It has recently become focus of attention due to its quick advancement to the 12th position in the recent TIOBE index and the overall rise in popularity.
What is F#?
F# is an open source, functional and object oriented programming language which is available in cross platform. It was developed by a company called F# software foundation with help of Microsoft and other open contributors. F# runs on Linux, windows, iOS, Android and the GPUs and HTML as well. It is a mature programming language which helps the users as well as the organizations to solve the complex problems in a much simpler way with easy code. With its wide range of usage in the specialist and application areas, it is proving itself to be a worthy contender for the top 10 list.
Why choose F#?
Information Technology is one of the most dynamic industries with new technologies surfacing frequently. In such a scenario, it can get intimidating for information technology professionals at all levels to keep abreast of the latest technology innovations worth investing time and resources into.
It can therefore get daunting for entry and mid-level IT professionals to decide which technologies they should potentially be developing skills. However, the biggest challenge comes for senior information technology professionals responsible for driving the IT strategy in their organizations.
It is therefore important to keep abreast of the latest technology trends and get them from reputable sources. Here are some of the ways to keep on top of the latest trends in Information Technology.
· Subscribe to leading Analyst Firms: If you work for a leading IT organization, chances are that you already have subscription to leading IT analyst firms notably Gartner and Forrester. These two firms are some of the most recognized analyst firms with extensive coverage on almost every enterprise technology including hardware and software.

However, subscription to these reports is very expensive and if you are a part of a small organization you may have issues securing access to these reports. One of the most important pieces of research published by these firms happens to be the Gartner Hype Cycle which plots leading technologies and their maturity curve.Even if you do not have access to Gartner research, you can hack your way by searching for “Gartner Hype Cycle” on Google Images and you will in most cases be able to see the plots similar to the one below
