One very useful method is to organize your material as if you had to explain it to another person. Select the best organizational strategy that fits this approach.

After you have arranged your material according to the organizational strategy you selected, further develop the material by:

• Providing an illustrative example for each main point and explain the relationship of the example to the point it supports.
• Using a variety of different kinds of support or proof for your statements, such as facts, statistics, examples, comparisons, testimonies (an eye witness account or a direct quotation), narrative (a story). This way you reach and persuade various members of your audience.
• Repeating key concepts/points by articulating the connections which support your organizational strategy, thereby reinforcing important points.

For example, for a speech on waste management, the best organizational strategy might be the problem-solution framework. You could structure the presentation as a series of key dilemmas, each one followed by a number of possible responses, the first being the ineffective response, and the second the better choice. Each time a problem is introduced, the listener could begin to anticipate a range of possible solutions and thereby become more receptive to the information that follows.

With a stellar organization your presentation also needs a frame to introduce and conclude it.
