Answer:
The change in complex systems can be explained according to the relationship of the environment where the system is implemented.
The system environment is dynamic, which consequently leads to adaptation to the system, which generates new requirements inherent to changes in business objectives and policies. Therefore, changing systems is necessary for tuning and usefulness so that the system correctly supports business requirements.
An example is the registration of the justification of the requirements, which is a process activity that supports changes in the system so that the reason for including a requirement is understood, which helps in future changes
Explanation:
Answer: D.) Personal Mission Statement
Explanation: The personal mission statement refers to a write up which is usually written by an individual and it's tailored to embody one's complete definition in terms of core values, skills, attributes and most importantly present and future desires, goals and objectives.

Answer:
TRUE
Explanation:
TRUE - A recipe for deducing the square root involves guessing a starting value for y. Without another recipe to be told how to pick a starting number, the computer cannot generate one on its own.
Answer:
1. FDD is a process and Analysts can use a FDD to create and use business functions and processes. It Requirements models are used when gathering requirements for a new system.
2. BPM is used on an ongoing basis for business process improvement. It is meant to improve order, insight and efficiency of the collective workflows that make up any given business process. BPM is meant to reduce any chaos within those collective workflows that make up a process and eliminate ad hoc workflow management. BPM means Business Process Management.
3. DFDs stands for Data Flow Diagram which will help software developers and designers to understand how they can take their next step to fit into the overall business process. DFDs paly key role for a successful requirements modeling.
4. UML can be used for modeling a system independent of a platform language. UML is a graphical language for visualizing, specifying, constructing, and documenting information about software-intensive systems. UML gives a standard way to write a system model, covering conceptual ideas.
Explanation:
Functional decomposition diagram (FDD) is used to identify functions and define their structure. It is a technique to decompose the complex problem into manageable pieces or individual elements to develop the application or product.
DFDs: It contains a process (shape) that represents the system to model, in this case, the "Food Ordering System". It also shows the participants who will interact with the system, called the external entities. In this example, Supplier, Kitchen, Manager and Customer are the entities who will interact with the system.
Unified Modeling Language (UML): Edraw UML Diagram is the application of choice for many software engineers and designers. The software is fully compatible with 64 and 32-bit Windows platforms from Windows XP to Windows 10.
