The portfolio is the professional presentation tool for many career fields, including graphic design, architecture, interior design and space planning, writing, web development, etc. It is more than just a collection of sample pieces. It reflects your skills, your habits and your personality as a professional. Employers will ask to see your portfolio, usually during an interview, to measure both the quality of your work and the professionalism of your presentation.
This is a marketing piece that supplements your full portfolio. The same basic portfolio rules apply, except you are using fewer pieces, copies instead of originals and a smaller porfolio binder/folder. If you do not yet have a full portfolio, developing a "Mini" is a good way to start the larger project.
The Mini-Portfolio can be a very effective marketing tool. It works very well when employers request samples with application materials. It's easier to target than a full portfolio, picking individual pieces for each distinct job or employer. The "Mini" can then be mailed or given to potential employers. And it can be carried with you almost anywhere you go.
The Mini-Portfolio should include an introductory piece , like a resume, and 4 - 5 samples of your work. For the visual presentation fields (drafting, graphic design, interior design, etc.), these will be reduced or partial samples of drawings and plans, or photographs of projects. Pieces should be reduced or cut to 8 1/2" X 11". Other career fields should also include an introductory piece with 4 - 5 samples. These can include written samples, spreadsheets, programming code, tool lists, photographs of projects, etc. Regardless of career specialty, you may also want to include letters of recommendation or other materials that show your strengths and abilities. Make sure you use an appropriate cover or envelope for a professional look.
