Level of Development and Level of Detail came into play with the advancement of computers and BIM technology. As the AEC industry began move towards using computer renditions for design and analysis, it became necessary to define the certainty with which drawings could be trusted. The detailing of elements changes throughout the duration of a project, so it is important for the team to be able to recognize what level of detail is provided and how trustworthy it is. For this reason, different levels of development were created to allow for a standardized system of analyzing drawings and details.
Level of Development vs. Level of Detail
The level of Development (LOD) enables construction teams to specify and distinguish the content and reliability of Building Information Models at various stages of the design and construction process with high levels of clarity and reliability. The LOD describes the minimum dimensional, spatial, quantitative, and qualitative data included in a Model Element to support the authorized uses associated with such LOD. Since each Model Element develops at a different rate, the Level of Development (LOD) framework allows the project team to understand the progression of a Model Element from conceptual idea to precise final definition and description. The LOD of a given Model Element informs other Project Participants how developed the information is expected to be. This allows participants to extent to decipher which that information can be relied upon, at a particular point in time in the developmental process. This prevent participants from using elements in an unintended manner.
Level of Detail refers to the actual amount of information(details) provided. Level of detail is generally thought of as an input to the element while Level of Development is considered a reliable output.
To summarize, Level of Development is a measure

During schematic design, the focus is on the "scheme", or overall high-level design. Here, minor details should be ignored to instead focus on creating a coherent solution that encompasis the project as a whole. A major focus of this phase is the relationship between rooms and spaces. Consider which spaces should be adjacent to one another and gradients of public vs private spaces when sketching out the layout of spaces.

To keep pace with growth, an intensive effort was launched to investigate and then implement a set of integrated tools and approaches to facilitate project planning and execution. Investing in a full suite of project planning, monitoring, and control mechanisms is a prudent and necessary step to ensure project delivery. This investment...

...Essential Features of Effective Communication 1. Listening is the No. 1 Rule Contrary to what some seem to believe, the most important aspect of effective communication isn’t talking, it’s listening. A great amount of miscommunication could be avoided if business owners took the time to communicate effectively, first by listening to the needs of their clients and prospects. Remember, your clients may not need you, but you definitely need your clients or you’re going to be out of business. 2. Clarity is Key What may be second nature to you may seem like a foreign concept to some people. When in doubt, leave out the jargon. However, if a client shows interest in understanding the small details, offer the acronym after you’ve explained what it means. The goal here is to be sure your clients understand what you’re specifically discussing. 3. A Message with Confidence Confidence is an essential role in being able to come across as a master of effective communication. If you demonstrate that you aren’t confident in your abilities, people will instinctively think that you lack experience and are bluffing your way. This may result in: A) the client tries to talk you down from your initial quote; B) the client doesn’t hire you at all; C) the client hires you at your original rate but isn’t confident that you can complete the task to his expectations. 4.
