Em determinadas situações, no entanto, essas técnicas de simplificação podem causar inconsistências e promover vieses cognitivos. Em se tratando de iniciativas de melhoria de processos de software, é importante que as práticas, técnicas, métodos e ferramentas sugeridos no processo ofereçam mecanismos para apoiar a tomada de decisão, minimizando os efeitos negativos de tais vieses. Este artigo se propõe, apoiado em uma metodologia qualitativa aplicada em duas empresas de TI no Brasil e em Portugal, a analisar oito vieses, a saber: ancoragem, efeito da mera exposição, viés retrospectivo, efeito halo, falácia do planejamento, falácia do custo afundado, viés da disponibilidade, e efeito da lei de Parkinson. Através de entrevistas semi-estruturadas com gerentes de projeto (GPs), foram identificadas causas raízes para cada viés, assim como métodos e ferramentas utilizados para minimizar seus efeitos negativos, os quais foram consolidados em um mapa de conceitos. Práticas ágeis e atividades de gestão do conhecimento foram citados como essenciais em processos de software tendo em vista à tomada de melhores decisões.

The rise of the "new economy", driven by information and knowledge, has led to an increased interest in intellectual capital theory, which aims to manage intangible assets of organizations. Firms belonging to technology and knowledge-based industries recognize intellectual capital as the key knowledge base that contributes to the creation of a competitive advantage for the firm. This paper aims to answer the question "How are Intellectual Capital (IC) and Information Technology (IT) related?" through a systematic review based on four steps: 1) search conduction; 2) selection of papers based on their titles and abstracts; 3) content analysis of selected papers; 4) evidence mapping and discussions. The analyzed papers were categorized into five themes: "Statistical analysis or case study in IT companies from the Intellectual Capital perspective"; "IT as a tool for Intellectual Capital Management"; "Intellectual Capital or technology knowledge assets influencing innovation and development", "Intellectual Capital assets to evaluate a technology" and "Intellectual Capital theory as a way to understand and share knowledge in IT projects". Our findings evidenced that the Human Capital was the main dimension studied by the authors, followed by Structural Capital and Relational Capital. We believe that this work may help to clarify on Intellectual Capital Management procedures into Information Technology projects, thus opening new topics for future research.

Quantitative assessments show that many Business Intelligence projects fail at an alarming rate. Extrapolated costs and delivery delays are attributed in large part to requirement problems, such as the difficulty of the customer to know what he/she wants, failures of communication between the development team and the customer, the development team’s lack of knowledge of the customer's business, different vocabularies between the customer and the technical team, the development team’s lack of the necessary social skills to extract and understand the strategy and customer needs, among others.
Given this reality, it is observed that the knowledge gained from the customer is critical for success in Business Intelligence projects. The customer knowledge is considered by the intellectual capital theory as an intangible asset, because it results from interactions. Furthermore, enterprises are increasingly worried about the satisfaction of their customers and looking for ways to guarantee their loyalty.
One of the objectives of this paper is to present a literature review about requirements management practices in existing business intelligence methodologies and about the main theory in intellectual capital, especially in customer capital dimension. Moreover, we believe that this review may help to understand the possible influence of the customer capital management to make explicit the customers' knowledge in Business Intelligence projects. As a result of the ongoing research we intend to examine the intangible assets of an information system development initiative and mechanisms proposed by the customer capital to evolve the interactions of an enterprise with the customer and improve the requirements definition of a Business Intelligence project. This paper also presents a study model that resumes the proposal of this ongoing research.

Besides, it also presents an initial evaluation of the acceptance of this process by the developers and analysts from one of the development units of the company. In general, the results obtained showed a good perception about the gains with the test automation process and a good level of satisfaction with the tools adopted by the company.

This is due to the inadequacy of the traditional characteristics intrinsic to the process of software maintenance, e.g., fast delivery, simplicity in the communication process and closer monitoring of problems. In this context, this paper aims to present the software process, scrum-based agile
model, adopted in the Maintenance Area of Dataprev / PB. At the end, we present the survey of subjective satisfaction of the maintenance team regarding adoption of that process.

The methodology aims to support strategic decision making and facilitate the alignment of software development processes to business goals of Information Technology organizations and it is based on software process improvement approaches, such as IDEAL Model, Cycle of Improvement ISO/IEC 15504 and DMAIC.
