A safety issue has been identified with a batch of Dimplex portable dehumidifiers. A component may overheat, resulting in the product catching fire.

A few further comments should be added about the single force that is a source of much confusion to many students of physics - the force of gravity. As mentioned above , the force of gravity acting upon an object is sometimes referred to as the weight of the object. Many students of physics confuse weight with mass. The mass of an object refers to the amount of matter that is contained by the object; the weight of an object is the force of gravity acting upon that object. Mass is related to how much stuff is there and weight is related to the pull of the Earth (or any other planet) upon that stuff . The mass of an object (measured in kg) will be the same no matter where in the universe that object is located. Mass is never altered by location, the pull of gravity, speed or even the existence of other forces. For example, a 2-kg object will have a mass of 2 kg whether it is located on Earth, the moon, or Jupiter; its mass will be 2 kg whether it is moving or not (at least for purposes of our study); and its mass will be 2 kg whether it is being pushed upon or not.

Tip 11. Sample Use Case Model Diagram You can use the use case modeling tool to produce a sample use case model within a few clicks. Once you define your use cases and actors, just go into the reporting section and click on the 'Use Case Model' report and that's it. See the image below for a sample of the use case model.

In several places in this document, I have stated "effective use cases" rather than just "use cases". The purpose of the use cases is for effective knowledge transfer from the domain expert to the software developer -- these use cases will serve as software requirements. If they don't make sense to the person building the software, they are not effective. There are several sources on the web for writing effective use cases including the book by Alistair Cockburn . Tip 12. What's the difference between a User Story and a Use Case? With so many engineering teams making the paradigm shift from waterfall to Agile Software Development , people often get caught up in having a pure Agile process which would include the use of User Stories. So what's all of the hoopla with User Stories? What are they, how are they different from use cases, do I need them, and where do they fit in the process?

  • What is a User Story? Simply put, written from the context of the user as a simple statement about their feature need. They should generally have this format. "As a -role-, I want -goal/desire- so that -benefit-"
  • How is a User Story different than a Use Case? While a use case is highly structured and tells a story, the User Story sets the stage by stating the need. A User Story is the prelude to the use case by stating the need before the use case tells the story.
  • How does the User Story fit into the process? User Stories are great as an activity in collecting and prioritizing the high level features. Getting this initial feedback from the customer is a simple way of trying to get all of their needs identified and prioritized. The User Stories will then morph themselves into the business requirements and use cases.
Tip 13. In Agile Development, Keep Use Cases Agile, Mean and Lean A common myth with Agile Development is that you *must* use user stories, and not use cases. Like anything else in life, nothing is black and white -- being Agile is really about smaller iterations, learning and adapting to the market.

If you are using Agile, Scrum and moving away from waterfall, what you want to do is make sure to iterate with your use cases. All that means is that your flows will be smaller and less feature rich. While the theme of the use case may appear the same from iteration to iteration, what is changing is the level of detail and the features inside the particular sprint.

Creating a use case to long winded with too many features can potentially put a product at risk. What happens is that you can extend your release to market from two weeks to several months without the ability to learn from the iteration and adapt to the market. Keep those use cases leaner!
