In this paper we identify best industry practices and current trends in the development and management of software products. We discuss the strategic importance of developing appropriate operational capabilities that are prerequisites for achieving marketing success. We illustrate these concepts with examples from software companies to highlight how they achieved the desired balance between market demands and operational resources. Finally, we highlight the benefits these companies had derived from such an alignment.

Indispensable Tool

Information systems outsourcing is an indispensable tool in the management of information systems. The set of services contracted to outside suppliers, originally more limited to services of an operational nature, has expanded over the past two decades, and today there is a wide range of services subject to outsourcing. Among them are: the hiring of software development; maintenance of applications; services and communications networks; security of information systems; and many others. Depending on the nature of the services contracted and on the range that the contracting of services has on departments of information systems, the issues involved in project management vary considerably. This article presents the results of a survey conducted among large companies in the Republic of Ireland to characterize, among other things, the range of services that are most often outsourced. The results are relevant in the sense that not only do they enable a better understanding of the reality of information systems departments of large Irish companies, but also enable the management to focus attention on specific services.

Modeling Paradigm

This chapter aims to present a new modeling paradigm that promises to significantly increase the efficiency of developing enterprise information systems. Currently, the software industry faces considerable challenges as it tries to build larger, more complex, software systems with fewer resources. Although modern programming languages such as C++ and Java have in general improved the software development process, they have failed to significantly increase developer’s productivity. Thus, developers are considering other paths to address this issue. One of the potential paths is designing, developing and deploying enterprise information systems using the Model Driven Architecture (MDA). MDA is a model-centric approach that allows for modeling the overall business of an enterprise and capturing requirements to developing, deploying, integrating, and managing different kinds of software components without considering any particular implementation technology. At the center of this approach are models; the software development process is driven by constructing models representing the software under development. Code that expresses the implementation of the model in a certain underlying technology is obtained as a result of model transformation. Thus, the intellectual investment spent in developing the business model of an enterprise is not jeopardized by the continuous changes of the implementation technologies. Currently there are two main approaches trying to implement MDA-based tools. One of the approaches is based on the Object Constraint Language and the other on Action Language. An example of designing, developing and deploying an application using this new modeling paradigm is presented. The MDA approach to software development is considered as the biggest shift since the move from Assembler to the first high level languages.

Design Requirements

Operators need situational awareness (SA) of their organisation’s computer networks and Information Systems in order to identify threats, estimate impact of attacks, evaluate risks, understand situations, and make sound decisions swiftly and accurately on what to protect against, and how to address incidents that may impact valued assets. Enterprise computer networks are often huge and complex, spanning across several WANs and supporting a number of distributed services. Understanding situations in such dynamic and complex networks is time-consuming and challenging. Operators SA are enhanced through a number of ways, one of which is through the use of situation-aware systems and technology. Designing situation-aware systems for computer network defence (CND) is difficult without understanding basic situational awareness design requirements of network applications and systems. Thus, this chapter investigates pertinent features that are foundation, essential, and beneficial for designing situation-aware systems, software, and network applications for CND.
