\begin{tabular}{p{42.7 pt} p{34.1 pt} p{34.1 pt}} \hline \hline \# & **Area** & **How Much and How** \\ \hline \multirow{2}{*}{1} & \multirow{2}{*}{PEG} & From start when using traditional/legacy development processes/methods/tools, etc. until later stages—a 50–75\% improvement regarding pace and efficiency. Thus, a significant saving of effort, time and costs. \\ \hline \multirow{2}{*}{2} & \multirow{2}{*}{DPP} & Usage of the Arrowhead Framework ([PERSON] et al., 2017; [PERSON] et al., 2018) and its requirement engineering and development process, as well as usage of strict Service-Oriented Architecture (SOA) principles, has enabled streamlined development and cooperation. \\ \hline \multirow{3}{*}{3} & \multirow{3}{*}{T} & Usage of the Arrowhead Framework to abstract IoT devices and sensors as services saves a lot of time and effort. Further, re-use and refinement of the data collection and analytic platform, together with re-use of analytic tools and frameworks, has further hastened development and improved efficiency. The addition of secure remote configuration and updating of the cloud software and sensor software has been key to scalable technical management and operational efficiency. \\ \hline \multirow{4}{*}{4} & \multirow{4}{*}{CS} & Firstly, whole new businesses (and customer segments) unfamiliar to us had to be learnt. We were also used to mainly providing products and services, and had to learn more about complex business models. Secondly, we needed to learn more about: cloud services, SOA, Arrowhead Framework, sensors, robust data and mobile communications, industrial internet/IoT, big data, data modeling and data analytics, and IT/information/cyber-security. In particular, the business parts, data modeling, data analytics and security have been challenging. Thus, this has been very challenging—but on the other hand developed the company considerably. \\ \hline \multirow{5}{*}{5} & \multirow{5}{*}{O} & It was necessary to change to a new business model i.e., IPS2, from a product with a services model. When changing the business model, with subscriptions based on 36–60 month contracts and the pricing depending on the volume, the business took off and the volumes rapidly started to grow. Further, we have started to set up partner networks in order to scale up the business and sales/marketing efforts. In addition, we had to win the trust of the customers by firstly knowing their business, and then having an offer that they found attractive. \\ \hline \multirow{6}{*}{6} & \multirow{2}{*}{M} & Internally, we have had to add missing competencies to the board of directors, and use long-term financial planning and strict cash-flow to not impede the fast pace of customer installations. \\ \hline \multirow{7}{*}{7} & \multirow{2}{*}{I} & We moved from an own operated cloud service to a green-powered cloud platform service provider, which has allowed us to focus more on technical- and business development instead of operations. Further, this is much more stable and we do not have to have the same number of people concerned with operations. \\ \hline \multirow{8}{*}{8} & \multirow{2}{*}{S} & We have learnt a lot by doing service and support, set up a service desk and support organization, contracted service partners, and have consequently developed e.g., health indices for sensors (i.e., battery level and function) and other equipment in order to reveal maintenance need for physical installation and ensure high availability of the decision-making information to the customers. \\ \hline \hline \end{tabular}

Table 1: Improvement and how a high development pace and efficiency has been accomplished at Adage AB. of approximately 70-80%. Thus, this ought to be of interest also for other companies and organizations involved in development activities related to the industrial internet and IoT. The eight areas in Table 1 are all interconnected as they rely on, support or depend on each other.
