Lack of flexibility Meant only for bigger projects Not suitable for projects where requirements are likely to change Once in the testing phase, it is difficult to go back and change aspects like functionality.
Development process is well-documented and scalable Progress is easily measured High-risk tasks are completed first Early involvement of developers. Can be expensive, creating a high cost and longer time to reach a final product Can be ineffective for smaller projects Highly customized, which limits reusability Needs special skills to evaluate the risks and assumptions.
Face-to-face communication and continuous inputs from customer representative leave no space for guesswork End result is the highest quality software in the least possible time Very realistic approach to development Suitable for fixed and evolving requirements. Documentation is created in later stages Reduce the usability of components Requires special skills and ongoing oversight Transfer of technology to new team members may be difficult due to lack of documentation.
Allows for more resources to be used in development More straightforward to manage Allows developer flexibility Good learning aid for students or newcomers. Harder to attain a firm grasp on requirements High-risk with high level of uncertainty Poor model type for long or ongoing projects Can be expensive if requirements are misunderstood and timelines are vague.

Data design elements The data design element produced a model of data that represent a high level of abstraction. This model is then more refined into more implementation specific representation which is processed by the computer based system. The structure of data is the most important part of the software design. Architectural design elements The architecture design elements provides us overall view of the system.

Covers classes in the package and packages within another package. Deployment diagrams are a set of nodes and their relationships. These nodes are physical entities where the components are deployed. Behavioral diagrams basically capture the dynamic aspect of a system.
These controllers are known as actors. Describes the flow of control in a system. It consists of activities and links. The flow can be sequential, concurrent, or branched. Represents the event driven state change of a system. It basically describes the state change of a class, interface, etc. Combines activity and sequence diagrams to provide a control flow overview of system and business process.
Each communication is associated with a sequence order, number plus the past messages. A model is a complete, basic, and simplified description of software architecture which is composed of multiple views from a particular perspective or viewpoint. A view is a representation of an entire system from the perspective of a related set of concerns.
It is used to describe the system from the viewpoint of different stakeholders such as end-users, developers, project managers, and testers.
It is a multiple view model that addresses different features and concerns of the system. It standardizes the software design documents and makes the design easy to understand by all stakeholders.
