Tacit knowledge is the knowledge that is acquired from one’s own experience, which cannot be easily expressed through words or pictures. It is personal, subjective, and based on intuition and insights. It is difficult to explain because it is often implicit, uncodified, and context-specific. Examples of tacit knowledge include facial recognition, riding a bike, or playing a musical instrument. References: Tacit Knowledge Vs.

Development cost is the type of cost that is considered as actual costs of analysis, design, and installation for the system. Development cost includes the expenses incurred during the planning, designing, building, testing, and deploying of a system. Development cost is usually estimated before the start of a project and is used to measure the feasibility and profitability of a system. Development cost is also used to monitor the progress and performance of a project and to control the scope and quality of a system. References: CITM Course Outline, Module 4, Corporate IT Strategy, page 9. CITM Training Course, Cost, page 14. CITM Certification Overview, Exam Information, Course Outline, Module 4.

The second step in System Analysis is to conduct a feasibility study, which is an assessment of the technical, economic, legal, operational, and schedule aspects of the proposed system. A feasibility study helps to determine whether the system is viable, beneficial, and achievable within the given constraints and resources. A feasibility study also helps to identify the risks, costs, benefits, and alternatives of the system. References: 1, 2, 3

An ER diagram (Entity-Relationship diagram) is a type of diagram that consists of object types and relationships. An object type is a category of objects that share common attributes and behaviors, such as a class, an entity, or a component. A relationship is a connection or association between two or more object types, such as an inheritance, an aggregation, or a dependency. An ER diagram is used to model the structure and semantics of a system, such as a database, a software system, or a business domain. An ER diagram can show the cardinality, optionality, and constraints of the relationships, as well as the attributes and operations of the object types. References: What is an Entity Relationship Diagram (ERD)?, Object Diagrams | Unified Modeling Language (UML), The Easy Guide to UML Class Diagrams | Class Diagram Tutorial, Class diagrams vs Object diagrams in UML
