The act of determining the time, resources, and cost needed for a software project.

Estimating software costs, schedules, and effort has become more challenging due to the increasing complexity of software systems.

Software's pervasive influence and continuous development are pushing its boundaries, leading to increased demands on software's capabilities.

Traditional hardware solutions are now being replaced by software systems, and entirely new products and services are emerging due to advancements in software.

The growth in size and complexity of software affects its cost, time-to-market, functionality, and quality requirements.

The development of genuinely new software requires creative problem-solving, more akin to creating a scientific theory than a manufacturing process.

Software's impact is far-reaching, extending to various areas of life such as goods, services, and industries.

Software development relies heavily on human abilities, creativity, and intellectual processes, making it more intricate than purely technical tasks.

Customers, developers, and other involved parties all play a crucial role in the success of a software project.

Software products are abstract concepts, making them difficult to visualize and manage compared to tangible objects.

Software development involves multiple transformations, with constant refinement and feedback loops throughout the process.

Tasks within a software project are interconnected, creating a complex web of dependencies.

The elusive nature of software requirements contributes to the challenges of measuring and managing software development.

Accurate estimation of time, resources, and costs is vital for the financial success of a software project.

Effective project management involves monitoring resources, analyzing market potential, and fostering a learning environment.

Software projects are business ventures requiring a clear justification, outlining potential benefits, costs, risks, and future options.

The relationship between the amount of work (effort), the time required to finish a project, and the number of people involved (staffing) is interconnected and influential. Changes in one factor affect the others.

A curve that represents the trade-off between the amount of effort required and the time needed to complete a software project, showcasing different combinations of effort and time.

The idea that putting more people on a project that's already behind schedule doesn't always guarantee faster completion. More people can create communication bottlenecks and increase management stress.

The area under the staffing curve in the Effort-Time trade-off is not always constant, meaning that adding more people to a project might actually increase overall effort due to coordination and management overhead.

An approach to estimating software development effort that involves analyzing past project data and using similar projects as a guide. While useful, this method should be adapted to specific contexts.

The practice of preventing defects early in the development process is more cost-effective than fixing them later.

The cost of fixing a software problem increases significantly the longer it takes to identify and fix.

The effort needed to fix a software issue after delivery can be 100 times higher than fixing it during the design phase.

A software development approach that focuses on testing and quality assurance only in later phases, often leading to significant rework.

A staffing curve that represents a project where a significant amount of effort is dedicated to early development phases, minimizing rework later.

A staffing curve that depicts a project where the peak staffing occurs during the later stages of the project, potentially leading to more rework.

A staffing curve that represents projects where a portion of the work has already been completed in the past.

Representing how project effort and staffing change over time throughout the software development lifecycle.

An empirical observation that describes how project staffing fluctuates during various stages of the development lifecycle.

The process of ensuring that the software meets its requirements and performs as intended.

When a target for a project is smaller than any reasonable estimate, it might be necessary to change either the target or the project scope to achieve alignment. This involves adjusting project factors like team capabilities, tool support, or the overall functionality and quality of the deliverables.

An iterative process where both the target and estimates are adjusted through negotiation until they align. This involves evaluating project factors, considering the project scope, and potentially adjusting project team capabilities or tool support.

A project management approach where the project target is set to be lower than estimated effort and resources. This often leads to unrealistic expectations and high pressure on developers to meet these targets.

The act of negotiating and agreeing upon the resources required for a software product or service with external contractors. Bids typically include the project price and the expected duration of the project.

A specific value representing the estimated effort and resources required for a project. Typically used as a basis for negotiation during bidding.

A process of adjusting project characteristics, such as team capabilities or tools, to improve development productivity and reduce the estimated effort required to meet the project target.

The process of negotiating the scope of work included in a project to match the pre-defined target. This involves adjusting the functionality or quality of the deliverables to achieve alignment.

A set of project components or deliverables that define the overall functionality and quality of the software product or service being developed.

The targeted outcome or desired goal of the project.

The estimation process involves actively aligning predefined targets with realistic estimates, which may require adjustments to project characteristics, project scope, or both.
