## 1 Introduction  
The transition towards Servitization in enterprises has been increasing continuously in the last decade. This process has been occurring in various industries, revolutionarily changing the landscape of an entire business, e.g., transforming goods manufacturers into service providers. Due to this, companies must undergo major changes. However, Servitization is a time-consuming and necessarily persistent process. It does not occur instantly; it is a long and continuous process. Thus, a company must know which phase of this process it is operating in to perform further accurate steps and succeed within a short time, because modern business competition is highly dynamic. Accordingly, an IT Servitization process analysis was the motivation for the research presented in this paper. Consequently, the transition towards Servitization in the IT Business is extremely challenging because IT Enterprises must transform partly or entirely from hardware manufacturers into service providers. This move happens as a part of \"Digital Transformation\"/\"Digitalization\" [1] of modern economy, or, in other words, a transition towards the \"Digital economy\" [2]. As evidence of this, \"Every day 207 billion emails are sent, 8.8 billion YouTube videos are watched, 4.2 billion Google searches are conducted, and 152 million Skype calls are made. Internet based, digital business are expanding at a tremendous pace, with new mobile and intangible digital goods and services becoming available to consumers on a daily basis.\" (October 2018) [1]. Furthermore, \"Today, half the world's population is online, a third are on a social network, 53% are mobile, and they span all ages, races, geographies and attitudes across the planet. The culmination of this explosion in consumer connectivity is the Digital Economy. A young, dynamic, $3 trillion ecosystem based on technological infrastructure, increasingly intuitive devices and interfaces, vast audience networks, a whole new medium for advertising and an unlimited supply of content.\"... \"It has disrupted age old industries while giving rise to completely new ones.\"... \"The Digital Economy is worth almost three trillion dollars today. To put it in context, this is about 30% of the S&P 500, six times the U.S.' annual trade deficit or more than the GDP of the United Kingdom.\" (Jun 16, 2016) [2]. Still, the current situation, as presented in Figure 1[2], reflects the dominance of \"digital\" manufacturing of software and services. As is found in [2], \"Device Systems and e-Commerce are 71% of the digital economy's value\" and \"they generate 80% of the profit\", while \"social media is 12% of the digital economy\" and \"generates 3% revenue and 5% profit\". On the other hand, the \"content over billion webpages... makes up 1% of the digital economy's value, revenue, and profit\". Besides, as is mentioned in [3], \"Digital technologies are driving unprecedented change, disruption, and opportunity in business, the economy, and society. As the pace of change accelerates, it's imperative that humans examine the most pressing question of our time: How do we thrive in a period of profound digital transformation?\"  
Consequently, Servitization transition reasonably envisions this question and also visualizes Digitalization, or the transition towards a digital economy, through real projects. As defined in [4] (Figure 2), \"The core of the digital economy is the \"digital sector\": more often called the \"IT sector\" or \"ICT sector\"\"; \"The \"digital economy\" is \"that part of economic output derived solely or primarily from digital technologies with a business model based on digital goods or services\"; \"A much wider scope encompasses all economic activity based on digital technologies; thus also including application of ICTs to intensify existing economic activity in manufacturing, services and primary production is \"digitalised economy\"\".
