Software Estimation Basics 1

Explanation
Effort for the development of software is commonly measured in hours. This is because the amount of time and effort put into the development process is a crucial factor in determining the overall success and quality of the software. By tracking the number of hours spent on development, organizations can better estimate project timelines, allocate resources effectively, and measure productivity. Additionally, using hours as a metric allows for easier comparison and benchmarking across different projects and teams.

Explanation
The correct answer is "Good Requirements and delivery model". This is because having good requirements ensures that all the necessary information and specifications are clearly defined, which helps in accurately estimating the cost and delivering the project successfully. Additionally, a good delivery model ensures that the project is executed efficiently and effectively, meeting all the requirements and delivering the desired outcomes. Therefore, both good requirements and a solid delivery model are essential for a good estimate.

Explanation
Underestimating is more costly than overestimating. This is because underestimating can lead to inadequate planning, insufficient resources, and potential failure to meet goals or deadlines. On the other hand, overestimating may result in excess resources or unnecessary expenses, but it allows for more flexibility and ensures that goals are more likely to be met.

Explanation
The correct answer is "Inception, Elaboration, Construction and Transition". This is the correct sequence of phases in the Rational Unified Process (RUP). Inception is the initial phase where the project scope and objectives are defined. Elaboration is the phase where requirements are refined and a detailed project plan is created. Construction is the phase where the actual development and coding of the software takes place. Transition is the final phase where the software is deployed and released to the users.

Explanation
The process "On-the-shelf" is not a software development process. This term typically refers to purchasing pre-built software or using off-the-shelf software solutions instead of developing custom software. It involves selecting and implementing existing software products that meet the organization's needs, rather than creating software from scratch.
