Can Large-Language Models Replace Humans in Agile Effort Estimation? Lessons from a Controlled Experiment

Effort estimation is critical in software engineering to assess the resources needed for development tasks and to enable realistic commitments in agile iterations. This study investigates whether generative AI tools, which are transforming various aspects of software development, can improve effort estimation efficiency. A controlled experiment was conducted in which development teams upgraded an existing information system, with the experimental group using the generative-AI-based tool GitLab Duo for estimation and the control group using conventional methods (e.g., planning poker or analogy-based planning). Results show that while generative-AI-based estimation tools achieved only 16% accuracy—currently insufficient for industry standards—they offered valuable support for task breakdown and iteration planning. Participants noted that a combination of conventional methods and AI-based tools could offer enhanced accuracy and efficiency in future planning.

Research on Robot Dynamic Path Planning Based on Multiple Linear Reinforcement Learning

Under the background of digital and intelligent transformation, all walks of life are facing the conflict between internal stability and rapidly changing external needs, and the conflict between stable background and dynamic foreground. To solve these conflicts and problems, it needs to take new means to adjust from multiple dimensions. Draw support from the new info and communication operation support system, it could form a digital Internet info support system with the cloud platform, which can effectively establish fast and flexible front-end utilizations and support the rapid development, agile iteration and on-demand adjustment of related businesses. The Internet backbone network needs to make the info open. The new info communication operation support system based on the Internet can enable the info resources to be transmitted as needed. The research and utilization of cloud resource visualization and controllability has gradually become the key to the development of new Internet communication operation system. On the premise of systematically combing the Internet info and communication operation support system, this paper comprehensively studies the utilization of cloud resources, and analyses the utilization scenarios of cloud resources of the new education communication operation system, in order to better ameliorate the more efficient and secure utilization of cloud resources and communication operation system inside and outside the enterprise.

Evaluating combined project management models: strategies for agile and plan-driven integration

The combination of agile and traditional practices is important for greater innovation in New Product Development (NPD). This paper analyzes ten combination proposals found in the literature, using the systematic bibliographical review method. Four of them did not show features associated with the combination. Four proposals recommend using agile project management associated with NPD process. Two proposals recommend using a general project plan, prepared through Work Breakdown Structure, scheduling, and integrated with agile iteration planning. The evaluation of these proposals indicated a shortage of recommendations and revealed two classes of combination strategies, namely bottom up and top down.

Client Communication: A Major Issue in Agile Development

Agile development model solved a lot of its predecessor the waterfall model problems like time, cost, resources and high risk of failure due to incomplete or inaccurate requirements. However, agile model introduced the client communication problem; due to the structure and nature of agile methodologies, it depends heavily on communicating with client. With four layers of communication that get repeated in almost every agile iteration, failing to handle client communication is one of the main reasons behind failure of agile based projects. In this paper, we survey the existing methods of communication which are classified into two main categories: physical meetings/workshops and software communication tools. Each category is assessed and compared based on certain attributes such as availability, productivity, cost, reliability, trust and project coverage. In addition, the available solutions to address the communication problem, which include enhanced physical meetings/workshops and software tools like requirement engineering tools, agile management tools and social media sites and applications, are analyzed and assessed based on attributes such as usability, formality and project coverage. The study revealed that the available solutions did not address all the aspects of the communication problem. Therefore, it is desirable to develop an integrated solution which utilized communication software tool using social media frameworks as its backbone and physical meetings to benefit from human interaction and relationships to solve the communication problem in agile environment.
