Integrating Project Management, Software Development, and Knowledge Management Models: A Case Study in a Public ICT Services Organization

In project-based organizations knowledge is a critical resource used to develop and deliver products and services with a high level of quality. Therefore, a systematic and sustainable process is necessary to coordinate knowledge management, project management and product lifecycle. This scenario predominates in companies focused on the creation and maintenance of information systems. This article presents an exploratory study based on a framework that integrates cognitive, managerial, and operational processes in a public Brazilian organization that provides services in the area of information and communications technology, focusing on the construction and maintenance of information systems. Those processes are operationalized by three management models considering knowledge, project, and software development processes. Our proposal aims to understand the relationships between those three management models and their influence on the software development process in the organization under study. Our premise is based on the principle that cognitive management, project management, and software development management must be integrated to fulfill the demands of product development and service provision. The research data was composed of registers of working hours spent on software development and maintenance projects involving 244 people allocated to 5064 projects in the period from 2007 to 2013. The study resulted in the identification of the relationships among the three management models adopted by the organization, with emphasis on knowledge management activities, which were not directly identified, making it difficult to account for and measure them. We established a set of activities connected to each one of the knowledge management model phases. Since those activities were not visible before, our approach contributed to build a systematic process to register and relate activities linked to the dimensions of cognitive processes, project management, and software construction.

A methodology for model clone detection using statistics of design metrics

Model clone detection has predominantly gained momentum in the field of software development process and model driven engineering. Reuse and mutations of the existing models will increase the complexity of managing the software’s organisation’s internal repositories. Detecting semantic and structural similarities among the models finds various uses like fault prediction, estimation of maintenance and refactoring. Literature in the domain witnesses very few works focussing on model clone detection. This work proposes a model clone detection technique by leveraging the statistical and lexical properties of the UML diagrams. The primary contribution of the work is the construction of Similarity Measure (SM) by analysing the design metrics from different perspectives namelyi)measuring the statistical variability between the models and ii) estimating the lexical similarity among design metrics. The results of the model indicates that the proposed method was able to detect the semantically similar model clones of the banking use case. Also, the method is very robust and computationally inexpensive, so that it could find its applicability in all fields where model driven engineering is used.

استخدام المنهجيات الحديثة لتطوير النظم في إدارة المعرفة والمعلوماتية الصحية

The importance of developing health care software emerged as a necessary process to transform the paper health care system into a computer-based information system to ensure the effectiveness, efficiency, and quality of health service provision, reduce medical errors and ensure patient safety. The importance of developing health care software also emerged due to the high degree of complexity of health care services, and the accuracy required to ensure that there are no errors. Healthcare software needs to comply with laws and regulations during its development, be more secure and stable than other software, and be high-performance without crashes. In reality, this is often not the common case, as you are going to release a poor-quality product and constantly improve it - you want your product to be trusted and used from day one. Agile software development is an iterative process that creates a usable software product from the early stages, enabling rapid, high-quality development that will respond quickly to changing requirements. The Waterfall model may be a good software development model in the case of large-scale software projects. However, there are many tradeoffs between the two software development approaches, Agile or Waterfall. This paper covers common software development methodologies and discusses the benefits and drawbacks of each of them, and how we can modify them according to the requirements of healthcare information systems. During this research, a hybrid software development methodology (Hybrid Scrum-Fall Model) was proposed to develop the health care system. The proposed model combines the agile Scrum development methodology with the Waterfall model to deliver quality software solutions that deliver greater value to the end user.

Implementation of The Patas Model in The Development of The Matana University Graduation Information System

There is an urgent need to make a graduation information system at Matana university. This system is needed, especially for students, secretariat, and finance. Several other things to consider, namely the number of participants and the graduation committee are more than 300 people, delegation of system development to one person, many users are still unfamiliar with integrated information systems based on information technology (IS/IT), the Corona pandemic, and can anticipate sudden changes. Therefore, we need a software development model that fits these conditions. The research methods for making this model, such as literature study, interviews, observation, model making and model testing (model application). This software development model is called Patas, it is fast and limited. This model has six stages, i.e., user needs, tools selection, modification, evaluation, implementation, and maintenance. This model is then applied to the development of a graduation information system at Matana University. The Matana University graduation information system has been successfully built using the Patas model. This system features prospective graduate registration, payment, sending information to participants (personal or mass) by email, dashboard, privilages user, attendance for graduates by barcode, change profile and content management. This graduation information system is used from graduation preparation to graduation day. Thus, the Patas model can be an alternative model in software development. In the future, the Patas model needs to be tested for the development of a different and larger system.

Property-Based Quality Measures in Ontology Modeling

The development of an appropriate ontology model is usually a hard task. One of the main issues is that ontology developers usually concentrate on classes and neglect the role of properties. This paper analyzes the role of an appropriate property set in providing multi-purpose ontology models with a high level of re-usability in different areas. In this paper, novel quality metrics related to property components are introduced and a conversion method is presented to map the base ontology into models for software development. The benefits of the proposed quality metrics and the usability of the proposed conversion methods are demonstrated by examples from the field of knowledge modeling.

Comparison Of Waterfall And Prototyping Models In Research And Development (R&D) Methods For Android-Based Learning Application Design

<p><strong>Design of learning applications that use Development Methods (Research and Development/R&D) using a commonly used system development methodology, namely SDLC (System Development Life Cycle). Several stages of SDLC consist of planning, analysis, design, implementation to system maintenance. The SDLC concept is the basis of various types of software development models to form a framework in planning and controlling information systems. The SDLC model that is often used in research and development (R&D) research for the development of Android -based learning applications is a waterfall and prototyping model. The comparison of the two models states that the waterfall model is more suitable for a system or software that is generic or in the form of software that can provide services to the buyer. While prototyping is more suitable for customize systems or software, meaning software made based on demand and needs (even certain situations and conditions). In accordance with the analysis obtained, the two methods have the advantages and disadvantages of each, so that the developer can choose which method is more suitable for the development of the software.</strong></p>

Detection Malaria Base Microscope Digital Image with Convolutional Neural Network

Malaria is a tropical disease that infects human red blood cells caused by infection with the plasmodium parasite. Plasmodium parasites spread to humans through female Anopheles mosquitoes and can reproduce in human blood cells. Malaria is a health problem that is at risk of causing other health problems such as anemia and even death. The current gold standard for malaria diagnosis is laboratory diagnosis by microscopic examination to find the malaria parasite through the blood cells of the patient. However, the diagnosis of malaria through microscopic observation of blood cells has the potential to take a long time, because the plasmodium parasite has a very small size. The malaria detection system using the Convolutional Neural Network (CNN) method is designed to detect malaria in human blood cells. CNN is a machine learning method designed to classify objects in an image. The system was built in three stages of development, namely the development of a CNN model for malaria detection, software development and hardware development. The hardware components used in the system include Raspberry pi, Raspberry Pi camera module, and LCD. The results of the malaria detection test using the CNN model gave an accuracy of 98.76% which was tested on blood cell images from a microscope

Multi-Level Testing Approach for Multi-Agent Systems

The software development cycles need product testing. There is a crucial lack in testing phases of multi-agent systems. To this end, a call for an investigation of appropriate testing techniques is necessary to provide adequate software development processes and supporting tools. Among all existing solutions of the test, the model-based testing technique –MBT) has gained attention with the popularization of models both in software design and development. This technique uses a so-called abstract test model to generate abstract test cases. After their concretization, concrete test cases are submitted to the system under test. The systems outputs are finally compared to the abstract test model expected results. In this context, a model-based testing approach for multi-agent systems based on the Reference net paradigm is proposed in this paper. A running example supported by a multi-agent testing prototype, which aims at simplifying and providing a uniform and automated way for multi-agent systems testing is presented and discussed.
