Why is the IT Industry flourishing?

  1. Since every working company is moving to digitization, IT companies working operations are the most in-demand with the kind of services they offer. They not only help move the client to digitization but also enhance the digital aspect of its working which contributes to IT company’s revenue model.
  2. Since services and products can be acquired from any source, clients can hire multiple companies at once for several projects and that provides a co-working space that helps innovation and bring forth the best possible service available.
  3. The subscription model of these services and products is the biggest aspect of the revenue generated by the IT companies. This business model helps clients understand requirements and tailor services to their needs, which gives rise to competition in the market.
  4. Since they work for the globalizing digital environments, the user base is possible all over the world without the requirement of travel or office set-ups.

Possible challenges for IT Companies

Competition is evident when we look at the IT industry. Every IT giant has similar, if not the same, services that they offer. The products differ as per the clients and that produces a never-ending competition in the market.

  • Cyberattacks

Since the companies handle personal data every day, this leads to a threat of security which needs to be tended to all the time. With digitization comes the threat, and that is a well-known fact.
