In this article the focus is on software evolution, which is an important part of software engineering. In practice, software development does not stop when a system is delivered but continues throughout the lifetime of the system. After the system has been deployed, external pressure for change can generate new requirements for the existing software. This change aspect, which is a characteristic of software engineering, should be taken into consideration when developing and modeling new software systems. In this paper the theme was studied using experience gained from the piloting of a reference system developed in an earlier research project carried out by T ampere University of Technology. Software evaluation is examined from the point of view of system developers, administrators (maintenance), and end users based on a concrete long-term piloting period. submittedVersion

A clean environment is often taken for granted, but when a river or a lake becomes polluted, it might be hard for the general public to verify the condition. A simple visualization tool for checking the condition of water could help to inform the public and help to increase environmental awareness. With the emergence of Open Data and other openly available data sources, it is possible to create new and innovative applications. In this paper we present a web-based tool for reviewing the quality of water by applying the River Heavy Metal Evaluation Index (rHMEI) method together with open data on water quality in Finland. publishedVersion

This thesis explores the technical and group work challenges present in implementing and utilizing real-time collaborative coding. This method of programming allows multiple programmers to edit the same files concurrently, however the technical implementations must be carefully considered as they can have a negative effect on group work. Different methods of document synchronization and code integration are presented and evaluated in order to find an optimal solution for real-time collaborative coding. Two existing code integration methods and one theoretical method are examined for their effects on group work. The suitability and effects of real-time collaboration on programming are examined through pair programming, classroom programming and outsourcing. The purpose of this thesis was to find optimal technical solutions among the various methods of implementing real-time collaborative coding and to evaluate the suitability of different models of programming in utilizing real-time collaborative coding. Certain superior technical solutions were found but some research issues still remain open. Excerpts from a previously made research publication that focuses on use of CoRED, a real-time collaborative IDE made at Tampere University of Technology have been included. The excerpts provide additional information on logging and visualizing collaboration in a classroom environment.

This thesis examines the organizational effects of digitalization. Barriers and facilitators of digitalization are studied as well. The thesis is divided into two parts: a literature re-view of the subject and an empirical study. The empirical study consists of codification of qualitative data collected by dr. Pertti Aaltonen as well as development of a G-Accelerate tool prototype. This thesis is a part of Need 4 Speed SRIA programs G-Accelerate project. Literature review presents findings of extant literature from different aspects of how digitalization affects organizations. Themes found in the literature are organizations size and shape, agility, digital innovations along with organizational learning and business ecosystems. Literature isolates organizational inertia and lack of understanding between top management and IT departments as barriers for digitalization. Main facilitators are top management support and competent IT departments. During the empirical research 13 categories were segregated from the data collected by dr. Aaltonen. The research was done using grounded theory methodology. Final catego-ries are: customer understanding, cooperation, ecosystems, business model design, ca-pabilities and competences, culture, performance indicators, leadership capabilities, customer’s customer, new business areas, management systems, organizational structures and process orientation. These categories were validated by having two researchers agree on the limits. G-Accelerate tool prototype was created based on the categories from the raw data. G-Accelerate tool is a psychometric questionnaire designed to find out organizational ca-pabilities, structures and processes regarding digitalization. Based on the answers it’s possible to offer guiding insights for management to support organizations efforts to digitalize.
