What is DET and RET in FP estimation?
DET – Data Element Type is a unique user recognizable, non-repetitive field. FTR – File Type Referenced is a file type referenced by a transaction. RET – Record Element Type is a user recognizable sub group of data elements within an Internal or External File.
What is FP count?
Advertisements. A Function Point (FP) is a unit of measurement to express the amount of business functionality, an information system (as a product) provides to a user. FPs measure software size. They are widely accepted as an industry standard for functional sizing.
Which are data functions in FPA?
Detailed FPA
| Data or transactional function | Function type | Complexity |
|---|---|---|
| Add Customer | EI | High |
| Change Customer | EI | Average |
| Delete Customer | EI | Low |
| Inquire on Customer | EQ | Low |
What is Functional Point Analysis?
Function Point Analysis (FPA) is a method or set of rules of Functional Size Measurement. It assesses the functionality delivered to its users, based on the user’s external view of the functional requirements.
Why do you think the FP need to be adjusted?
FP metrics is used mostly for measuring the size of Management Information System (MIS) software. 10. These (UFPs) of a subsystem are further adjusted by considering some more General System Characteristics (GSCs). It is a set of 14 GSCs that need to be considered.
What is RET and DET?
Record Element Type (RET): A RET is user recognizable sub group of data elements within an ILF or an EIF. Data Element Type (DET): A DET is a unique user recognizable, non-recursive (non-repetitive) field. A DET is information that is dynamic and not static.
How is FP calculated?
- Step-1: As complexity adjustment factor is average (given in question), hence, scale = 3.
- Step-2: CAF = 0.65 + ( 0.01 * 42 ) = 1.07.
- Step-3: As weighting factors are also average (given in question) hence we will multiply each individual function point to corresponding values in TABLE.
How is FP count calculated?
- Cost Estimation.
- For each function identified above the function is further classified as simple, average or complex and a weight is given to each.
- FP = total UFP * (0.65 + (0.01 * Total complexity adjustment value)) or.
- FP = total UFP * (Complexity adjustment factor)
What are various types of FP function point?
Types of FP Attributes
| Measurements Parameters | Examples |
|---|---|
| 1.Number of External Inputs(EI) | Input screen and tables |
| 2. Number of External Output (EO) | Output screens and reports |
| 3. Number of external inquiries (EQ) | Prompts and interrupts. |
| 4. Number of internal files (ILF) | Databases and directories |
What is record element type?
A record element type is a user recognizable subgroup of data elements within an ILF or EIF. A data element type is a unique user recognizable, non-recursive, field.
What is the formula of VAF in FP calculation?
The score of all 14 GSCs is totaled to determine Total Degree of Influence (TDI). Then Value Adjustment Factor (VAF) is computed from TDI by using the formula: VAF = (TDI * 0.01) + 0.65.
What is the difference between a Det and a FTR?
File Type Referenced (FTR): A FTR is a file type referenced by a transaction. An FTR must also be an internal logical file or external interface file. Data Element Type (DET): A DET is a unique user recognizable, non-recursive (non-repetitive) field. A DET is information that is dynamic and not static.
How to identify record element type ( Ret )?
Record Element Type (RET): A RET is user recognizable sub group of data elements within an ILF or an EIF. It is best to look at logical groupings of data to help identify them. The concept of RET will be discussed in detail in the chapters that discuss internal logical file and external interface files.
How many dets are required for a RET?
It is recommended that a RET must comprise at least 2 DETs exclusive of primary and foreign keys and effective dates to satisfy the condition of a sub-group of information. If in doubt, FP Analysts should not count a sub-group of information as a RET.
Which is not an optional Det in IFPUG Ret?
The IFPUG RET definition implies that one optional or repeating DET is not a subgroup. For example, the marital status of an Employee may be ‘Married’ or ‘Single’. If ‘Married’ a Spouse name is recorded.
