The waterfall life cycle model of software development is best suited for situations where the project requirements are well understood. The waterfall life cycle model is a sequential and linear approach to software development that consists of several phases, such as planning, analysis, design, implementation, testing, and maintenance. Each phase depends on the completion and approval of the previous phase before proceeding to the next phase. The waterfall life cycle model is best suited for situations where the project requirements are well understood, as it assumes that the requirements are clear, stable, and fixed at the beginning of the project, and do not change significantly throughout the project. The project is subject to time pressures is not a situation where the waterfall life cycle model of software development is best suited, as it may not be flexible or agile enough to accommodate changes or adjustments in the project schedule or timeline. The waterfall life cycle model may involve long delays or dependencies between phases, and may not allow for early feedback or delivery of software products. The project intends to apply an object-oriented design approach is not a situation where the waterfall life cycle model of software development is best suited, as it may not be compatible or effective with the object-oriented design approach. The object-oriented design approach is a technique that models software as a collection of interacting objects that have attributes and behaviors. The object-oriented design approach may require iterative and incremental development methods that allow for dynamic and adaptive changes in software design and functionality. The project will involve the use of new technology is not a situation where the waterfall life cycle model of software development is best suited, as it may not be able to cope with the uncertainty or complexity of new technology. The waterfall life cycle model may not allow for sufficient exploration or experimentation with new technology, and may not be able to handle changes or issues that arise from new technology.
