Errors in a requirements model have prolonged detrimental effects on reliability, cost, and safety of a software system. It is very costly to fix these errors in later phases of software development if they cannot be corrected during requirements analysis and design. A Use Case diagram, as a requirements model, plays an important role in giving requirements for a software system. It provides a ...

Use case models are used in object-oriented analysis for capturing and describing the functional requirements of a system. Attributes of a use case model may therefore serve as measures of the size and complexity of the functionality of a system. Many organizations use a system's use case model in the estimation process. This paper reports the results from a study conducted to evaluate a method...

This Internet of things is one of the most trending technology with wide range of applications. Here we are going to focus on Medical and Healthcare applications of IOT. Generally such IOT applications are very complex comprising of many different modules. Thus a lot of care has to be taken during the requirement engineering of IOT applications. Requirement Engineering is a process of structuri...

Architectural reuse promises the highest benefit when applied in a systematic manner, combined with the reuse of entire suites of artefacts ranging from requirements templates to pieces of code. In this paper, we present the concept of an architecturebased development process that is consequently oriented at reuse in all development stages. The development steps in this process are performed by...

The Blackblot Product Manager’s Toolkit ® (PMTK) is a comprehensive set of models and professional templates which constitute a complete product management methodology that illustrates notable best practices and processes to help create successful market-driven products. At the very core of the Blackblot PMTK Methodology are two foundation rules which govern the entire methodology. This chapter...

In the previous chapter it became evident that the Zimbabwean space economy is very unequal in terms of socio-economic development and that there are several development problems. Over the years the Zimbabwean government, like other governments in countries with severe spatial inequalities in development, has adopted various policies and strategies to obtain a more equal spatial distribution of...

This paper proposes a software process model based on the detailed description of software processes properties for the reuse and classification of their components. The proposed approach adopts the explicit separation of the main dimensions on process modeling. Also, the APSEE-Reuse system adopts a Case-Based Reasoning (CBR) approach to identify the similarity between the problem (the set of d...

This paper chronicles the development and feasibility testing of a computerized scheduled gradual reduction program for smokeless tobacco cessation. During Study 1, the LifeSign smoking cessation computer was adapted for use with smokeless tobacco by pairing it with an electronic timer. The computer recorded frequency of dips during a baseline phase and prompted for tobacco use during a gradual...

developing reliable yet flexible software is a hard problem. although modeling methods enjoy a lot of advantages, the exclusive use of just one of them, in many cases, may not guarantee the development of reliable and flexible software. formal modeling methods ensure reliability because they use a rigorous approach to software development. however, lack of knowledge and high cost practically fo...
