Use Cases for Business Analysis The use case is a method for documenting the interactions between the user of a system and the system itself. Use cases have been in the software development lexicon for over twenty years, ever since it was introduced by Ivar Jacobson in the late 1980s. They were originally intended as aids to software design in object-oriented approaches. However, the method is now used throughout the Solution Development Life Cycle from elicitation through to specifying test cases, and is even applied to software development that is not object oriented. This course identifies how business analysts can apply use cases to the processes of defining the problem domain through elicitation, analyzing the problem, defining the solution, and confirming the validity and usability of the solution. What you will Learn You'll learn how to: Apply the use case method to define the problem domain and discover the conditions that need improvement in a business process Employ use cases in the analysis of requirements and information to create a solution to the business problem Translate use cases into requirements Getting Started Introductions Course structure Course goals and objectives Foundation Concepts Overview of use case modeling What is a use case model?

About this Virtual Instructor Led Training (VILT) This Virtual Instructor Led Training (VILT) course presents advanced methodologies that implement demand response and energy conservation programs in light of the integration of new technologies, regulatory changes and the accelerated penetration of renewable energy resources. This VILT course provides examples and case studies from North American and European jurisdictions covering the operational flexibilities on the demand side including requirements for new building codes to achieve zero net energy. The course describes a public agency's goals and objectives for conserving and otherwise reducing energy consumption and managing its demand for energy. This course presents the demand response implemented for economics and system security such as system balancing and relieving transmission congestion, or for system adequacy. The course also presents the principal attributes of conservation programs and the associated success criteria. In a system with increased penetration of renewable resources, demand response provides flexibility to system operators, helping them to maintain the reliability and the security of supply. Demand response is presented as a competitive alternative to additional power sources, enhancing competition and liquidity in electricity markets. The unique characteristics are discussed from a local, consumer centric and also from a system perspective bringing to life the ever changing paradigm for delivery energy to customers. Interoperability aspects and standards are discussed, as well as the consumer centric paradigm of Transactive Energy with IOT enabled flexibilities at system level, distribution networks and microgrids. The VILT course introduces the blockchain as a new line of defense against cyber threats and its increasing application in P2P transactions and renewable certificates.

Customer care, customer service, Moccasin Approach,

Learning Centre Support Specialist, Learning Support Assistant,

We communicate daily in many ways, including email, phone, text, Zoom, Teams, Google Meets, Slack, and even that old-fashioned thing, what was it now... oh yes, talking face-to-face. But, when we look at communication closely and really drill down into what we are doing in conjunction with how our brain works (neuroscience), how internal, organisational, and social politics control what we believe we can say, how hierarchical positioning impacts our honesty and how the lack of psychological safety means we say what we know others want to hear rather than what they need to hear…. It is oh so complicated! This workshop not only explores the concept of excellent communication, but we also want to hear what you believe it is too. We also delve into how organisational culture influences our perception of speaking up. Factors that hinder open and honest communication, and we work collaboratively towards removing these barriers to achieve a communication style that fosters trust and transparency, creating psychological safety. This workshop is particularly relevant to our Emotional Intelligence workshop (EI and Me). We firmly believe that developing emotional intelligence is the key to unlocking Clean Communication, a skill that is crucial for all of us, regardless of our roles and responsibilities, so that we thrive in our professional environment. If you want to see if we are correct, why not have us facilitate a workshop for you and see what you get by the end of it?  LENGTH - Normally, one day. But please contact us to discuss your specific needs, or we can offer advice. NEXT WORKSHOP START - Please ask for more information as we deliver bespoke closed events for your people at your location or a mutually suitable location. WORKSHOP DELIVERY - The best environment for this workshop is face-to-face, but we can facilitate this workshop online. Suitability - Who should attend? Who Should Attend and Why? Who? - Perhaps think of this another way… who shouldn’t attend to ensure we can attain Clean Communication? There’s your answer. Why? - Every person needs to understand what we are saying above about how we get trapped in this organisational formatting which changes how we communicate and how it prevents us from communicating cleanly. EVERY organisation has this, despite what our values profess. And 'Values', that’s a whole other story. Workshop Content Using the 'Moccasin Approach'® to clean our personal and organisational communication LaPD’s Communication Cycle and what we must consider. (Can you work out what the ? represent above? Accountability and Responsibility raises its head in Communication. It has to. Bias, unconscious bias and its impacts on our communication. The conundrum of communicating with others and their styles (The TRAP). How would my perfect Manager/Leader communicate with me? Nonverbal communication (body language), rapport, Clean Communication. Negative communication can go viral (Self-Fulfilling Prophecy). Reflections, findings and goals (individual and team). Meeting our workshop objectives by listing five areas for development. Workshop delivery and venue This workshop is usually one day in duration, and it focuses solely on how we communicate with each other. It can also be a two-day event incorporating aspects of Emotional Intelligence (EI) with group, and individual activities to allow discussions about the various communication we need in your organisation. When you consider the content we deliver, we are sure you will understand why we always prefer to deliver our workshops, courses and programmes face-to-face. Face-to-face workshops and courses can be held at a location of your choice or, if you wish, a central UK location, such as the Macdonald Burlington Hotel in Birmingham, located directly across from the Birmingham New Street train station. We can deliver our workshops, courses and programmes online, although this will mean splitting elements into manageable learning events to suit the online environment.
