QUALITATIVE COMPARISONS OF ELICITATION TECHNIQUES IN REQUIREMENT ENGINEERING

It is often emphasized that the quality of elicited requirement is mostly influenced by the elicitation techniques employed to gather software requirements. Many elicitation techniques have been presented in requirement engineering but they are hardly adopted in practice as the available empirical and comparative evaluations are inadequate to guide the software industry on which technique is better. Classifying a selection of seven requirement elicitation techniques as collaborative, individual or contextual, this study compares the popular techniques using two groups of qualitative criteria - terms of information collection and quality of feedback information. The evaluation results are tabulated and the findings are depicted by spider diagrams. The study concludes that each technique has its strengths and weaknesses, the factors software engineers should weigh when selecting appropriate techniques for requirement elicitation

Finite state representation of reduplication processes in Igbo

This paper presents a finite state model of reduplication processes in Igbo. Identified Igbo reduplication processes are based on (i) verbal reduplication with prefixation, (ii) total nominal reduplication (iii) ideophone reduplication. However, this work identifies and includes a fourth and fifth type that occurs in the language, namely; (iv) adverbial reduplication and (v) prepositional reduplication. Xerox Finite State Tool (XFST) was used in representing the five Igbo reduplication processes computationally. Igbo verbal reduplication exhibits selective reduplication process and is characterized by prefixation and vowel replacement. Vowel harmony phenomenon was taken into consideration in achieving verbal reduplication to cater for phonological changes. Model testing results showed 84% accuracy in both analysis and recognition of reduplicated forms in Igbo

A Systematic Mapping Study of Innovative Cloud Applications

Abstract Cloud computing is a business paradigm wherein computers and computing related services are provided by Cloud Service Providers to consumers either as software, development platform, or infrastructure. Innovative applications are growing in a productive manner on the cloud landscape. Innovative applications are being developed for use in the area of e-learning, automotive processes, cloud containers and machine learning. The objective of this paper is to conduct a systematic mapping study of innovative cloud applications and experiences. The systematic map provided a structured overview of research work carried out and the frequency of publications, presenting them pictorially in form of a map. The obtained results showed that 7.34% of the publications were on development of innovative cloud applications in terms of model. Architecture and modelling, and simulation in relation to model were both at 13.76%, 11.93% of the papers respectively, while 8.26% of the articles were on deployment in terms of process. Architecture had most publication in the area of solution research, with 15.2%. For articles published on deployment and development, most were on solution research with 8.80% and 14.40% respectively. The outcome of this study will be beneficial to practitioners in the industry and academic researchers alike.</jats:p

Impact of Problems Associated with Scheduling and Capacity Planning of a Production Process – An Overview

Production is one of the most important activities which guarantee the continued existence of man; however, it comes with its challenges which make it very difficult to meet up the consumer’s demand. In this regard, the system is required by production and manufacturing companies, human resources, and materials to be enhanced by scheduling and planning of production. In addressing this problem of scheduling over a mid-term possibility, material flow and production objectives should be forecast by solving the problems of planning. Only when the production planning problems have been solved then scheduling problems could be addressed. In this work, we relate scheduling with capacity planning in relation to the production of goods and services. Also reviewed the common problems associated with the industry and how they are overcome.</jats:p

The Role of Production Planning in Enhancing an Efficient Manufacturing System – An Overview

Every manufacturing system can only survive with a high level of system planning and budgeting. Production planning is a sequential ladder in the manufacturing setting to ensure that materials input (raw materials, men, money, and machine) is made available within a stipulated time frame, in the appropriate amount to produce the demanded output of goods and services based on the schedule specified. Production planning also helps in making available high quality of goods and services in the right quantities to the customer at the demanded delivery timing to attain higher degree of customer satisfaction. Through production planning, different departmental activities i.e., engineering, production, purchasing, sales, and marketing, as well as stock control department, and other units that may relate to production are coordinated to attain a regular, steady, and balanced flow of production thus, enhancing reduction in production cycle time. Production planning serves as an instrument which estimates to gear up the performance of different departments and individuals of an organization in such a manner that will enhance better service to customers, fewer rush orders, more efficient use of equipment, reduced idle time of both machine and personnel, improved plant morale, good public image, and lower capital requirement, it may also create alternative plans to meet any form of emergency or contingency during the cause of production. From the foregoing, a manufacturing system that incorporates production planning in its operations will be more efficient, effective, and economical as compared with those that did not.</jats:p

A SYSTEMATIC REVIEW OF REQUIREMENT ENGINEERING PRACTICES IN AGILE MODEL

Requirement engineering practice (REP) are developed from requirement engineering processes to guide the engineers in requirement definition. Even though, the practices in agile present a few restrictions and open up several challenges to software industry, they help to address difficulties of conventional models and avert unnecessary cost. However, there are no clear-cut separation of these practices into their individual processes since the practices are closely used and the requirements are ever dynamic. Using Quasi-Gold standard to develop the search strategy and validating the same strategy by Snowballing, this study adapted Kitchenham guidelines to perform a systematic literature review towards identifying the common REP and the extent at which the REP are imbibed in software engineering. Requirement Management is the most popular practice while pre-testing is barely noticed. Eight of their associated challenges are identified and solutions discussed. REP is fully accepted in software engineering going by the annual rise in their discussions but future works is required on the detailed analysis of the root cause of these challenge
