1 assessed for quality before coding begins. LAB1 Assignment Order the following tasks in terms of the waterfall model: acceptance testing, project planning, unit testing, requirements review, cost estimating, high-level design, market analysis, low-level design, systems testing, design review, implementation, requirement specification.Implementation is the part of the process where software engineers actually program the code for the project.Software testing is an integral and important part of the software development process. This part of the process ensures that defects are recognized as early as possible.Documenting the internal design of software for the purpose of future maintenance and enhancement is done throughout development. This may also include the writing of an API, be it external or internal. It is very important to document everything in the project.Design: Software design is a multi-step process that focuses on data structures,software architecture, procedural detail, and interface characterization. The designprocess translates requirements into a representation of the software that can beassessed for quality before coding begins.
2 2-Draw a diagram that represents an iterative life cycle model.
3 3-Draw a process model for the task of painting the walls in a room 3-Draw a process model for the task of painting the walls in a room. Include the following tasks: choose color, buy paint, clean the walls, stir the paint, and paint the wall.
4 4-Why should tasks in a process model be separated by an artifact 4-Why should tasks in a process model be separated by an artifact?, and Why can’t it start until its input artifacts exist?The design of functions and the interface cannot be separated from each other in .... Carroll argues that we should view the artifacts created by designers as HCI ... Can we put an artifact under the spotlight and discern its uses; never the tasks are assumed to remain the same throughout the design process
5 5-Draw a DFD for a simple library system, showing its two main tasks, the first which cataloging new books in order to be ordered on the Bookshelf, and the second task which borrowing a book if exists on the shelf and returning it after borrowing
