1.You are the new Chief Design Officer (CDO) of a start-up, DTUI Inc. The project is to design a system for selling pottery. The aim is to develop an interface that meets the needs of both the potters and the customers. Describe in detail a design methodology of four stages to facilitate the proper design of such a system. Write your answer in the form of a management plan for this project. For each stage, indicate the number of weeks that should be allocated. Hint: Note the four phases of the design process: • Requirements analysis • Preliminary (conceptual) and detailed design • Build and implementation • Evaluation For questions 2–4, refer to the following scenario: The State of Maryland is developing a web-voting interface. For selecting the candidates, one design (RB) is a set of radio buttons and another is (CB) a combo-box (drops down when selecting the scroll arrow icon), both using standard fonts at 10-point size. 2. Compare these two designs when there are four candidates…

Monitoring is concerned with achieving a balance of the three dimensions of a project. Explain how the balance of these elements takes place in managing a project?
Project Scope Management Khan, (2006) (see below) states that, "Managing the scope of a project is the most important function of a project manager ... Effective scope management of a project also ensures the success of key completion areas, including time, cost, and quality. Project scope management can be further subdivided into its components which include: project initiation, scope planning, scope definition, scope verification, and scope change control." Based on your Integrated Project: Select two of the subdivisions above and discuss the primary issues that could arise from the process. Your response should begin with a definition of the selected subdivision before detailing the selected process
