What is PPM?
Precision Property Measurements (PPM) is a full service on-site measuring and CAD drafting firm, specializing in the creation of “as-built” site plans and floor plans, which depict the current state of a building or site. PPM’s mission is to offer the best combination of professional service, price, speed and accuracy that can be found in the industry. Based in Long Beach, California, PPM is currently serving all of the greater LA / Orange County areas. We also take on projects in San Diego and Ventura Counties. Our clients include a wide range of landscape, architectural and real-estate professionals, as well as property owners that need accurate plans of their homes or commercial buildings. We serve everyone from sole proprietor landscape architects that only do a project every couple of months, to large companies that have a dozen projects a week.
Project Portfolio Management (PPM) is a business tool used to effectively manage a number of portfolios or projects towards an overall objective. Each individual project is created in order to achieve a specific business objective or advantage. They should all benefit the overall project portfolio. The PPM is an umbrella for all of the individual projects. It is important to know what benefits each individual project has within the PPM system. A number of questions need to be asked to ascertain this. These include finding out how well each project is performing. You also need to know if any single project could have a negative effect on any other projects to come. Ultimately, you need to know that the successful outcome of all the projects will deliver the desired objective or benefit. Within a PPM system, there comes a point at which you have to evaluate the process. This evaluation determines whether each individual project is working satisfactorily through its life cycle.

(Parts per million) Click here for print version PPM (Parts per million) is a measurement used today by many customers to measure quality performance. Definition: One PPM means one (defect or event) in a million or 1/1,000,000 There was a time when you were considered a pretty good supplier when your defect rate was less than 1%, (10,000 PPM), then the expectation was increased to 0.1% or 1,000 PPM. Now the rate for most automotive components is targeted at 25 PPM or 0.0025% To calculate: For example, let’s say you had 25 pieces defective in a shipment of 1,000 pieces. 25/1000= .025 or 2.5% defective. .025 X 1,000,000 = 25,000 PPM. Use the PPM Calculator: Let’s put it in perspective. Let’s say, you produce 10,000,000 parts per year for your customer. If you’re like most companies, your plant operates around 5 days a week, 50 weeks per year or 250 days a year. Let’s assume your customers requirements are 25 PPM. That means that you would be allowed 25 pieces for every 1,000,000 pieces o
PPM stands for Pulse Position Modulation and is a term describing the concept for encoding using the scheme that came into being in the early 1960’s. The concept is the encoding scheme itself; not to be confused with modulation. The only form of modulation permitted for R/C systems in those days was Amplitude Modulation (AM). PPM in communications is based on taking a signal (Voice, music, et al) and operating on the continuously variable analog signal at sampling intervals with a voltage-to-pulse generator. The higher the amplitude of the signal, the closer the pulses are together and the higher the frequency of that variation, the faster the variations in pulse position occur. At the receiving end, whether by wire or radio, you can pass the pulse train through an integrator and reconstitute the original analog wave. The R/C decoder, instead, sorts out the variation from one pulse to the next in a very specific frame of pulses. It then converts a serial stream of data pulses into para
