The book supports the developers of services and applications for mobile phones, PDAs and smart phones. This new emerging domain is characterized by a very fast pace of change in the underlying technology, exposing products and applications to a constant risk of obsolescence. The relative youth of this field means that knowledge is comparatively limited.The book identifies an approach to mitigate the above risks by focusing on:The development processThe underlying technology and its effects on connectivitySoftware architecturesDeveloping Services for the Wireless Internet offers state-of-the-art technological knowledge and practical know-how to both practitioners – project managers, software architects and designers, process engineers and quality assurance workers, as well as academics and researchers looking to broaden their theoretical outlook. This book is an essential tool for all working in this field.

Right context, software reuse promises high value to businesses that develop software, opening the door to radical improvements in their software capability (productivity, cost, time to market). Attempts to adopt reuse without a sound understanding of the range of issues involved, however, can lead to expensive failure. This book is for those who are wondering whether they should adopt reuse and how, and also to those who have already started to adopt it but are wondering where they may be going wrong and how they could do better. It consistently emphasizes the practical issues that influence success or failure in reuse; and it offers a concise and balanced coverage of the essentials of the subject, rather than going into undue depth or detail on some topics at the expense of others. It occupies the central ground between being on the one hand an academic textbook and on the other hand a cookbook with ready-made recipes for exactly "how to do it". The authors have drawn on their extensive experience of reuse and of software process improvement to provide a readable and balanced coverage of the subject.This book is suitable for business executives, software managers and software developers, regardless of whatever kind of software or applications are developed by their organisations, and whatever the size of those organisations. A special feature of the book is the frequent use of experience notes, drawn from the real-life experience of organisations that have embarked on the reuse adventure.

This book constitutes the refereed proceedings of the 21st International Conference on Product-Focused Software Process Improvement, PROFES 2020, held in Turin, Italy, in November 2020.

Due to COVID-19 pandemic the conference was held as a hybrid event.The 20 revised papers, including 14 full papers, 3 short papers and 3 industry papers, presented were carefully reviewed and selected from 48 submissions.

Software reuse as an umbrella concept has been around for several decades. Over time, new techniques and approaches have been proposed to implement the concept, from libraries of reusable assets to product lines, to generative methods. These latter techniques are mostly used in intra-organizational reuse, and require considerable formal knowledge over the evolution of technology and required functionality in a domain over several years. On the other end of the spectrum, extra-organizational reuse is based on reuse of off-the-shelf (OTS) software (both open and closed source, acquired for free or for a fee). Here, a limited investment and immediate availability of the assets have widely spread the approach. On the other hand, the reusing organization has no control on the evolution of the functionality and assumptions of the asset. Even when the assets are open source, they are seldom modified. The theme for this ninth meeting is the reuse of off-the-shelf (OTS) components and related problems: * Documentation of OTS components * Processes to identify and select OTS components * Integration and evolution problems * Reliability and security of OTS components and legal issues * Interaction with the developer community or with the vendor The proceedings you are holding cover these issues as well as development and use of product lines, variability modeling, aspect-based development, composition of components and services.
