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:

Case Studies

Case Studies

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it.

Social Proof

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Persuasion Strategies

Persuasion Strategies

Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

Data Collection by Survey

Data Collection by Survey

The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...

Convenience Sampling Method

Convenience Sampling Method

Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
Convenience sampling is a non-random method of sample selection; this method selects individuals that are easily accessible and may result in biased data. For example, a marketing...

Background:

Crowd-based Requirements Engineering (CrowdRE) involves many stakeholders in requirements elicitation.
Existing research often focuses on crowd size rather than the quality of elicited ideas.
Online platforms are used for crowds to generate ideas for requirements.

Purpose of the Study:

To present the CREUS method for crowd-based elicitation using user stories.
To conduct a qualitative analysis of elicited ideas' quality.
To provide findings applicable to CREUS and general CrowdRE via pull feedback.

Main Methods:

Iterative design with three case studies across two organizations.
Application of Quality User Story framework criteria.
Automated text readability metrics and vague word analysis.
Assessment of user story linkage to software qualities and idea specificity.

Main Results:

Quantitative data on participants, ideas, and votes were collected.
Qualitative analysis revealed insights into the quality of elicited user stories.
Six key findings were distilled regarding the CREUS method and CrowdRE.

Conclusions:

The CREUS method offers a structured approach for crowd-based requirements elicitation.
Qualitative analysis is crucial for understanding the value of crowd-generated ideas.
Findings contribute to improving CrowdRE practices, particularly through user stories.
