The past decade has seen an increasing interest in IT outsourcing as it promises companies many economic benefits. In recent years, IT paradigms, such as Software-as-a-Service or Cloud Computing using third-party services, are increasingly adopted. Current studies show that IT security and data privacy are the dominant factors affecting the perceived risk of IT outsourcing. Therefore, we explic...

This thesis attempts to answer the following research question: “how can we determine and improve data quality?”. A method is proposed to systematically analyse the demands and current state of data quality within an organisation. The mission statement and information systems architecture are used to characterise the organisation. A list of data quality characteristics based on literature is us...

Risk management for software projects is intended to minimize the chances of unexpected events, or more specifically to keep all possible outcomes under tight management control with making judgments about how risk events are to be treated, valued, compared and combined. It is necessary to have some well-founded infrastructure for the identification of software security risks as well as the app...

An IT risk assessment must deliver the best possible quality of results in a time-effective way. Organisations are used to customise the general-purpose standard risk assessment methods in a way that can satisfy their requirements. In this paper we present the QualTD Model and method, which is meant to be employed together with standard risk assessment methods for the qualitative assessment of ...

The increasing ubiquity of information systems in organizations has been accompanied by a rise in users adopting technology that is not officially mandated (often known as shadow IT). This study examines the emergence and consequences of such locally-driven but centrally-unintended adaptations of an organization’s collection of IT assets. This phenomenon, referred to as “IS portfolio drift, can...

Achieving the design and construction of high-quality facilities that meet owner and endusers requirements is one of the triad of project objectives, the others being time and cost. Despite efforts by both practitioners and researchers, producing superior quality construction products on a consistent basis continues to be a challenge faced by all in the construction industry. Provided in this p...

In this paper, we showed how to quantify the quality of IT forecasts based on Boehm’s cone of uncertainty and DeMarco’s Estimating Quality Factor. With these, we support decision making by providing critical information on IT forecasting quality to IT governors. We illustrated that plotting forecast to actual ratios against a predefined referential conical shape reveals potential biases, for in...
