A productive response to legacy system petrification
Requirements change. The requirements of a legacy information system change, often in unanticipated ways, and at a more rapid pace than the rate at which the information system itself can be evolved to support them. The capabilities of a legacy system progressively fall further and further behind their evolving requirements, in a degrading process termed petrification. As systems petrify, they deliver diminishing business value, hamper business effectiveness, and drain organisational resources. To address legacy systems, the first challenge is to understand how to shed their resistance to tracking requirements change. The second challenge is to ensure that a newly adaptable system never again petrifies into a change resistant legacy system. This thesis addresses both challenges. The approach outlined herein is underpinned by an agile migration process - termed Productive Migration - that homes in upon the specific causes of petrification within each particular legacy system and provides guidance upon how to address them. That guidance comes in part from a personalised catalogue of petrifying patterns, which capture recurring themes underlying petrification. These steer us to the problems actually present in a given legacy system, and lead us to suitable antidote productive patterns via which we can deal with those problems one by one. To prevent newly adaptable systems from again degrading into legacy systems, we appeal to a follow-on process, termed Productive Evolution, which embraces and keeps pace with change rather than resisting and falling behind it. Productive Evolution teaches us to be vigilant against signs of system petrification and helps us to nip them in the bud. The aim is to nurture systems that remain supportive of the business, that are adaptable in step with ongoing requirements change, and that continue to retain their value as significant business assets

Investigating factors affecting software maintenance in e-commerce companies in Jordan
The most costly phase in the software life cycle is the software maintenance phase. It consumes between 40% and 90% of a software project’s budget. Software applications play an important role in e-commerce companies and the significance of software systems and their maintenance cannot be ignored. In order to improve the software maintenance process, a comprehensive understanding of the different factors involved in software maintenance in e-commerce companies is necessary. Thus, this study aims to identify and investigate the key factors that influence the software maintenance relevant to e-commerce in the country of Jordan. Furthermore, it hopes to provide a framework to address factors that affect the context described. A preliminary study was conducted in order to gain an insight into software maintenance issues faced by e-commerce companies in Jordan and also, to obtain further details of the main study requirements, such as participant numbers.This study adopted an interpretivist philosophy, qualitative approach. It was conducted in six e-commerce companies in Jordan. Each company was divided into two groups: Group A represents employees who work in software maintenance; Group B represents senior management of e-commerce companies. The total is 15 participants: 9 participants from Group A and 6 participants from Group B. Semi-structured face-to-face interviews, documents and archival records were selected as the data collection instruments for this study. Also, the qualitative data was analysed using NVivo software application. The findings of the study revealed that there is an absence of systematic approach regarding work in software maintenance in e-commerce companies in Jordan. Moreover, the study contributes to knowledge regarding the key factors that affect software maintenance activities in e-commerce companies in Jordan. Twenty-three factors were identified in the study as factors that affect software maintenance and those were classified into five main categories: human resources, organisation environment, operational environment, software characteristics and external factors. Also, the research contributes new knowledge by identifying three new factors affecting software maintenance: native language, operation users, and views of people about software maintenance jobs. Furthermore, the study developed a framework for software maintenance processes in e-commerce companies in Jordan to improve the effectiveness of maintenance work and reduce the negative impact on company operation
