Control Systems

Control Systems

Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.

Biopharmaceutical Factors Influencing Drug Product Design: Overview

Biopharmaceutical Factors Influencing Drug Product Design: Overview

Rational drug product design integrates knowledge of the drug’s physicochemical properties, formulation components, manufacturing techniques, and intended route of administration. Each factor influences the drug’s performance, including how it is released, absorbed, and eliminated in the body.The physicochemical properties of a drug—such as solubility, stability, and particle size—affect its compatibility with excipients and the choice of dosage form. Excipients, though...

Response Surface Methodology

Response Surface Methodology

Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:

Nursing Clinical Information System

Nursing Clinical Information System

Nursing Clinical Information System (NCIS)
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:

Mechanical Systems

Mechanical Systems

Mechanical systems are analogous to to electrical networks where springs and masses play similar roles to inductors and capacitors, respectively. A viscous damper in mechanical systems functions similarly to a resistor in electrical networks, dissipating energy. The forces acting on a mass in such systems include an applied force in the direction of motion, counteracted by forces from the spring, a viscous damper, and the mass's acceleration. This interplay of forces is mathematically...

Self-Evaluation Maintenance Model

Self-Evaluation Maintenance Model

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Area of Science:

Software Engineering
Systems Thinking
DevOps

Background:

DevOps pipelines accelerate software delivery but struggle with dynamic quality attribute management based on customer needs.
Implementing customer-value oriented quality requirements within existing DevOps practices presents a significant challenge.

Purpose of the Study:

To design and evaluate a systems thinking-inspired model, the Software Product System Model (SPSM), for holistic implementation of quality requirements in DevOps.
To demonstrate the application of SPSM in a large software house, focusing on dynamic quality gate control driven by customer feedback.

Main Methods:

Developed the Software Product System Model (SPSM) with a customer-value focus and holistic approach.
Integrated customer requirements and feedback into a product backlog to dynamically control quality gates within a DevOps pipeline.
Conducted a 2-year case study in a large software house, measuring security vulnerabilities and unit test coverage.

Main Results:

SPSM deployment led to a 69.50% decrease in security vulnerabilities and a 29.43% increase in unit test coverage.
Achieved a 99.50% project completion ratio and a 99.78% Schedule Performance Index (SPI) across 762 projects.
Demonstrated successful adaptation to changing customer expectations through SPSM's flexibility.

Conclusions:

The Software Product System Model (SPSM) effectively enhances DevOps pipelines by dynamically managing quality attributes based on customer value.
SPSM significantly improves key performance indicators related to software quality, project completion, and schedule adherence.
The model's design facilitates replicability and adaptability, offering a practical solution for software houses aiming to align development with customer expectations.
