ISD is a planning tool for developing instruction and materials for learners. It helps the instructional designer cover all aspects of the ADDIE model of Assess, Design, Develop, Implement and Evaluate when planning instruction. There are many different models in ISD and the designer would need to select a model that works best for the learning situation or themselves. The strength of ISD is that no stone is left unturned: the designer will touch on each aspect of ADDIE, sometimes repeatedly in some models. The designer gets the whole view of the process by systematically gathering information and analyzing it in order to determine the learning needs of the learner. Feedback and evaluations then continue the process where it may loop back around to the assessment aspect and start the process all over again. Change is a constant in ISD and it must be repeated to accommodate changes.
A drawback is that it takes time to go through the systematic process of ADDIE, but I believe the strengths outweigh this weakness. It’s better to take the extra time to complete the task to create effective learning than to skip some steps and end up with a sub-par product.
As an instructor, I’m pretty sure I have used ISD to develop my computer classes. I have assessed the needs of my students on the first day of class by asking them if there is anything else they want to learn in addition to the syllabus. I find out what their current knowledge is and start teaching from what they already know. I look for materials, websites and practice and drill lessons for them to complete to learn what they are missing in the needs analysis. Then when the instruction is over, I ask questions about the material or ask them to complete a task to see if they understand what was taught or if they feel comfortable with what they learned in class that day. If they still feel there is a gap or need, then I will search for alternative methods of teaching the new concept. I also like to review at the beginning of the class on what was presented in the previous class in order to reinforce the new concepts learned. From this feedback, I determine if we need to cover the same material again or move on to new material. ISD and ADDIE seem to be an ongoing process.

Excellent point about it being on-going. It is only by using this part of the model that true change is achieved. And I guess that is what scares most people about ISD--it is a tool to bring about change. And sometimes we get too comfy in our own predicatable patterns and traditions.
I know that it does take time to plan using the process but I agree with you that it is worth it. Sometimes I feel that there is not enough time in the day to plan as well as I would like to. I am trying to focus on time management this year so that I can become efficient in my teaching.
Sounds like you're quite adept at using the ADDIE model "on the fly." That is much more of a challenge than the fairly-well controlled environment in which I use it.
