A Symons Mark II Function Point Counting Example
I provide, here clear explanations and a count of function points, using the Symons Mark II method. We start by identifying the subprocesses (entry, exit, read, write) for each functional process; The size of a functional process is the sum of its data movements (entry, exit, read, write) and the size of a piece of software is the sum of the sizes of all of its functional processes. So the Function Point Index (FPI) for an application is: FPI = Wi * SNi + We * SNe + Wo * SNo, where ‘S‘ means the sum over all Logical Transactions, and the industry average weights per Input Data Element Type, Data Entity Type Reference and Output Data Element Type are, respectively: Now here is an example of this in practise, intended to demonstrate the practicalities of performing the count, see the Simmons counting point manual (CPM) for information about the rules used. Specification: The system should be able to have sales details entered, including the type and number of each product in each sale This allows a receipt to be printed for the customer. It also allows the inventory(stock) to be automatically updated. It should be possible to add new products, delete existing products, or modify the recipe of a product. It should be possible to produce a product report listing all the products available. As well as listing each product, this report will also show, for each product, the product no., the product description, its constituent item nos., item descriptions, and quantity used. A weekly report should be produced automatically, each Monday at 8am, showing the quantity of each product sold in the previous week. The process of sending orders to suppliers is not shown in the model. This is because each authorised supplier has access to the restaurant system and is expected to dispatch a standard quantity, with its invoice note, when the stocks of any items which it supplies fall below the minimum order quantity. When a consignment arrives from a supplier, it should be possible to enter on the system the details of the items/quantities/prices, so that the inventory(stock) is automatically updated. At the end of each month the accountant inspects the invoices and pays the bills. It should be possible for her to record that an invoice has been paid. Access to the system is through a single menu. Generic assumptions: 2) As per rule 1 of the CPM, only functional requirements directly referenced in the user specification are considered, corrections are only made to provide such functionality therein. 3) Given that there is no historic data about effort required in previous systems, I have used the following industry standards weighing: 0.58 for Wi, 1.66 for We and 0.26 for E0. 4) The intention is to present an abstract, theoretical view of the major entities and relationships needed for management of electronic resources. 5) This pizza restaurant is not very service oriented and does not allow customers to mix and or match toppings. 6) This is a 'McDonald' style system where products are quantity controlled by weight. Transactional Functions: Assumptions: 2) “Product_Description” is assumed to be a summary entry of about 60 characters, including the name 3)Product entity requires the attribute “Type_Of_Item”, to store category data, there is a distinction between the manufactured goods sold such as soft drinks and the pizzas that are created in-house. Inputs: 2) Select product type (business); User choses from categorised drop-down list of pizza related product types [Product: Type_Of_Item]. 3) Select product “name” (business); User choses from a drop-down list of pizza related goods. [Product: Product_Description > Receipt_No & Product_No]. 4) Select number of item (business); Customer may order 3 large margarita pizzas [Item_sale: Quantity_Sold]. 5) Confirm sale (control); This is a recursive menu selection system. Outputs: Entities: 1) Sale; Occurrence of a sale recorded here [Write All data]. 2) Item_sale; Functional relationship to sale entity (List of products for this sales) [Write all data]. 3) Recipe; Required to determine the inventory items to be subtracted from the inventory_item entity [Read all data]. 4) Inventory_item; Required to change the inventory(stock) level for items used [Read Item_No, Write Quantity_In_Stock] (Quantity of Item x - Recipe:Quantity_Used). 5) System; Provides the automatically generated sales receipt number and Date. FPI count: (0.58*5) + (1.66 * 5) +(0.26*1) = 11.46 [b] Add new products (External input);
Assumptions: 2) The inventory included food items and related products such as recipe ingredients for the piazzas and both the can, boxes and plastic utensils. Inputs: 1) Select new product (control); User action expressed by selection of command [Product: Product_No, Recipe: Item_no, Inventory_item: Item_no]. 2) Select type of item (control); Required for product classification [Product: Type_Of_Item > Inventory_item: Type_Of_Item]; 2a) Or enter new product type (control); 2b) Enter product type name (business); [Product: Type_Of_Item]; 3) Enter product description (business); Product description [Product: Product_Description]. 4) Select item (business); [Recipe: Product_no > Inventory_item: item_no]. 4a) Or enter Item Description (business); Goods description, [Inventory_item: Item_Description]. 4b) Enter stock level (business); [Inventory_item: Quantity_In_Stock]. 4c) Enter item reorder level (business); [Inventory_item: Minimum_Order_Quantity]. 5) Enter quantity (business); Quantity of the item per sales unit a bit ridiculous for products that do not require ingredients [Recipe: Quantity_Used]. 6) Add ingredient to product (control); Optional, not all products require additional items. 6a) Enter Item Description (business); Good description, [Inventory_item: Item_Description]. 4b) Enter stock level (business); [Inventory_item: Quantity_In_Stock]. 4c) Enter item reorder level (business); [Inventory_item: Minimum_Order_Quantity]. Outputs: 1) Error/conformation (control); End of sales data interaction cycle. Entities: 2) Recipe; Link entity, for the inventory required to deliver the project [Write all data]. 3) Inventory_item; Stores the stock data for the goods ,[Write all data]. 4) System; Provides the automatically generated product and item numbers.. FPI count: (0.58*14) + (1.66 * 4) +(0.26*1) = 15.02 [c] Delete existing products (External input);
Assumptions: 2) Here Delete refers to the recipe entry. Inputs: 2) Select product type (business); User choses from categorised drop-down list of pizza related product types [Product: Type_Of_Item]. 3) Select product “name” (business); User choses from a drop-down list of pizza related goods.

Continue [Y/N]” Outputs: Entities: 2) Recipe; Stores the inventory data required for the product, [Read all data]. FPI count: (0.58*4) + (1.66 * 2)+ (0.26*1) = 5.9 [d] Modify product recipe (External input);
