Use Case Table one.

It is not clear what this product is or does. You jump around between Consumers as actors and developers and testers. A Use Case should be a clear example of an actor using your product to achieve a specific result.

ID and Name	Requesting information about food ingredients and the nutrients value.
Primary/Secondary Actor	Consumers
Description	The consumer selects specific kind of food from the system, for which the consumer wants to check the ingredients.
Trigger	Consumer clicks on the food ingredients Why?
Precondition	Consumer is logged into the system. The Consumer has at least one count with personal authentication credentials. The system has listed various kinds of food.
Post condition	The type of food selected has been dispensed. This does not match the Normal Flow
Normal Flow	The system shows the accounts for different users. The account owner picks the desired account. The account owner chooses the kind of food to see the result. What does this accomplish\?
Assumptions	The system displays the type of food not selected.

Use Case Table two

ID and Name	Inquiring about the expiry date of food.
Primary/Secondary Actor	Consumers
Description	The consumer chooses a given type of food, for which he/she is interested in knowing the expiry date.
Trigger	Consumer clicks on point indicated for the information about until the date the food will be safe for human consumption.
Precondition	Consumer is allowed the access into the system. After filling the correct personal information, such as username and password. The Consumer has at least one count with personal authentication credentials. The system has listed information about various kinds of food.
Post condition	The specified type of information that the customer is inquiring about is displayed.
Normal Flow	The system shows the accounts for different users. The account owner picks the desired account. The system asks about the food to display. The customer selects the kind of food he/ she is interested in. The system displays the food item selected by the customer. The owner of the account selects the expiry date of the selected food. What is the state of the system when this terminates?
Alternate Flow	The system shows the accounts for different users. How is this different? The account owner picks the desired account. The system asks about the food to display. The customer selects the kind of food he/ she is interested in. The system displays the food item selected by the customer. The owner of the account selects the manufacturing date of the food. The customers check the longest time the food can stay while fit for human consumption.
Assumptions	The expiry date provided by the manufacturer is a genuine date.

Use Case table three

ID and Name	Testing the system.
Primary/Secondary Actor	Software team.
Description	The testing engineers who are part of the software team, test the functionality of the system.
Trigger	The testing engineers operates the system.
Precondition	The case for testing is set, the guidelines detailing on how to perform the testing are well outlined. the program setting, testing environment and the requirements necessary for conducting the test.
Post condition	This includes the information describing the outcome of the test, and how the system would after the test. The testing outcome is generated.
Normal Flow	The engineers create the testing environment for the better-quality testing. Creation of test cases for the testing process as well as setting the standard for which the system must meet for it to be considered of the right quality. Choosing the data to be used during the testing process. Performing the of test. Identification and Reporting of any kind of defects in the system. Regression testing, to identify the side effects that results from the testing process. Log defects, which involves the fixing of system defects. Retest, this is where the testing engineers retests the system, or performs the test afresh if in case the first testing was not successful.
Assumptions	The modules of the system being tested has been coded to completion. The testing is done before the system is released for use by other users.

Use Case table four.

ID and Name	Designing and developing the system.
Primary/Secondary Actor	Software team
Description	The team of developers who are part of the software team, builds and implements the system as well as responding to feedback and making the necessary adjustments for the system to function as desired.
Trigger	The developer codes the system.
Precondition	The necessary resource for implementing the system is identified and acquired. Computers to be used are prepared for the task. The right platform of coding as well as the compiler. The language to be used in coding is determined.
Post condition	By using the right compiler, the system the modules are tried as units and then integrated to come up with the system.
Normal Flow	The developers prepare computers, obtain the Integrated Development Environment (IDE), the suitable compilers. Following the system design, Developers start coding. The modules are tested. Integration of the modules is done to generate the system.
Alternate flow	The developers prepare the computers, obtain the right IDE, Why would this alternate take place? Development Environment (IDE), the suitable compilers. Without following any design, the developers start coding with the idea of the software in their minds, Testing the modules Integration of the modules to form the system.
Assumptions	The right design is followed.

Use Case Table five.

ID and Name	Building the sensor smart labels.
Primary/Secondary Actor	The software team.
Description	The software team will create a software that is necessary for the monitoring and identifying the taste of the food taste, in addition the software will help in determining the quantity of bacteria in the food bacteria quantity in the food.
Trigger	The testing engineers activates the sensor.
Precondition	A sample of food to be tested is dispensed into the software.
Post condition	The software indicates the taste of food to determine whether it is suitable for human consumption The quantity of bacteria is determined.
Normal Flow	The food sample is prepared. The Sensor is used to identify the taste of food. The sensor Is used to determine the quantity of bacteria in the food.
Assumptions	The sensor is not biased. The sensor is not compromised so that the outcomes can be accurate.

Use Case table six.

ID and Name	Dividing and transporting food.
Primary/Secondary Actor	Retailers
Description	This is the team that acts as the intermediate between the wholesalers and the consumers. They help in dividing the food into small portions and transport the food from the wholesaler’s premises to where the consumers are located.
Trigger	Dividing food into small portions.
Precondition	The food is manufactured appropriately and is of the right quality. The food has been tested and the bacteria levels are not to the extent of causing harm to the consumer.
Post condition	The food is divided into smaller amounts desired by the consumers and transported to reach he consumers
Normal Flow	The retailers get food from the wholesaler. They divide the food into small portions They transport the food to the location of the consumers The retailers deliver food to the consumer. .
Assumptions	The food is transported within the right time to avoid the food reaching their expiry dates before delivery.

Use Case table seven.

ID and Name	Controlling the food production and cost.
Primary/Secondary Actor	Government
Description	The team from the government Controls the production of food so as to ensure that the right ingredients are used, and the right procedures are followed in the production process. And lastly ensure that the food is of the right quality. In addition to that the control on the cost of food by the government is to prevent the exploitation of consumers by the retailers and wholesalers by right prices.
