Continue the business model of your project described in Assignment 1. Based on the use cases description, sequence (or collaboration) diagrams, define a correct and complete state-chart for your project. Identify which design patterns are appropriate for implementing the state-chart into Java programming language.Project – Finding the right word for the company’s phone Name – Fahim Faiaz LID – L20548798 Business Model for the project Service-based business model will be suitable for the project. Service-based business model is a type of business model where a company offers services to customers in exchange for payment. This could include services such as consulting, healthcare, education, legal services, or any other type of service. Service-based businesses may operate in a wide range of industries and can be either online or offline. Services can have high-profit margins because there are often few production costs involved, and the company can charge for the expertise and time of its employees. Starting a service-based business can be relatively inexpensive, as it typically does not require significant investment in physical products or equipment (Taran, Goduscheit and Boer, 2019). Service-based businesses can be highly flexible in terms of when and where services are provided, allowing the company to adapt to changes in demand. Since services are often provided directly to customers, service-based businesses can build strong relationships with their clients, leading to repeat business and positive word-of-mouth referrals. Service-based businesses can specialize in specific areas or industries, allowing them to become experts in their field and differentiate themselves from competitors. Service-based businesses can often scale quickly by hiring additional employees or contractors to provide services, without the need for significant investments in infrastructure or equipment. Use cases and use case diagram Use cases of the project includes: Branding: Finding the right word for a company's phone can be an important part of creating a strong brand identity that resonates with customers. A well-chosen name can help differentiate the phone from competitors, create a positive brand association, and make it easier for customers to remember and refer to the phone. Marketing: Once a name has been chosen, it can be used as a key part of the company's marketing strategy. The name can be incorporated into advertising campaigns, social media posts, and other promotional materials, helping to build awareness and generate interest in the phone. Product development: Choosing the right word for a company's phone can also help guide the development of the phone's features and capabilities. It includes a name that emphasizes simplicity might suggest a user-friendly interface, while a name that emphasizes power might suggest more advanced technical specifications. Customer feedback: As part of the process of finding the right word for a company's phone, the company can solicit feedback from customers and potential customers. This can help the company understand what words resonate with their target audience, and what features and benefits are most important to them. Figure 1: Use Case Diagram Sequence diagram Figure 2: Sequence diagram Feasible domain model and class diagram Behavioral Domain Model is the feasible domain model that can be used in the project. It is the type of domain model that focuses on the interactions and behaviors of the various entities (or actors) within a system. It describes the sequence of actions and events that occur between these entities as they perform a specific task or process. In the context of software development, a Behavioral Domain Model is typically used to represent the functionality and behavior of a software system, which can then be used to guide the design and implementation of the software. It provides a clear and concise representation of the system's behavior, which can help developers and stakeholders to better understand how the system works (Enayat, Łełyk and Wcisło, 2020). By mapping out the interactions between entities, a Behavioral Domain Model can help to identify requirements and use cases for the system, which can then be used to guide the development process. It provides a common language and visual representation of the system's behavior, which can help to facilitate communication and collaboration between developers, stakeholders, and users. This can be used as a basis for testing and validation, as it provides a clear and concise description of the expected behavior of the system.
