The answer depends on what you want to do with the numbers. Start your measurement process using the GQM process outlined above by targeting these areas and begin communicating results immediately to get support and buy-in.

Rather than sticking to GoF design patterns, the book looks at higher-level patterns. By the end of this book, you’ll be well on your way to becoming an expert Vue developer who can leverage design patterns to efficiently architect the design of your application and write clean and maintainable code. Experts advise on starting any measurement program in a small way first, gain buy-in with the measurement results, BEFORE rolling it out to an entire company.

There are software packages available on the icpug to aid in estimating accuracy. Towards the end, we’ll look at common antipatterns to avoid, to save you from a lot of trial and error and development headaches. Do we want to ifput a complete baseline done in a few months?

Depending on the application, many software developers and development teams recognize that a considerable amount of their work effort is not directly accountable using function ifput. By using bot function points and SNAP, project managers can better justify their budget; they can show their sponsors that more assets are built into the software — functionality, measured by function points, and non-functional aspects, measured by SNAP.


There are no industry standards ISO or otherwise for c;m lines of code. Quality means different things to different people.

Some things to think about: Developers invest effort in ifpuh the non-functional requirement. Software size can help management to estimate the return on the investment on their IT projects, and compare alternatives with a cost-benefit analysis. Lines of code tend to reward profligate design and penalize concise design i. Bigger code does not necessarily mean more productive when it comes to lines of code.


Iifpug to meet others in the measurement field; Educational opportunities to learn and earn continuing education credits through workshops held prior to the conference; Access to training and certification testing to earn globally recognized certifications including: User definable inputs that cross the application boundary and trigger unique processing i. It can be used cautiously on legacy systems without much prospect of further work. Please connect with us on Facebook and LinkedIn and share within your circles.

The FP results a listing of the counted business processes and their component functional size provides is in user-understandable terms. All other benefits are currently free of charge. The next step is to research available industry data particularly useful for companies who have not already collected historical FP data such as the data available from ISBSG.

We want to improve our quality, what information do I need to have? This is similar to how real and imaginary numbers are represented: We want to improve our estimating process by using FP, what other information do I need to have?

It provides a more fair and welcome measurement approach. Function point-based measurement and SNAP gives you a means to communicate with your customers the size of their software requests, and also allows you to easily calculate productivity, quality, and estimating accuracy.


FP have the advantage of being technology and implementation independent, while SLOC has the following disadvantages: An application baseline is the size of the current functions provided to the user by the system.

Refer to Guidelines to Software Measurement — Release 1. If you find yourself here, you may want to bring in a consultant to: If your goal is to be able to accurately assess how much change enhancement or growth happens throughout the year through software enhancements, then you might want to do a baseline count. Access to the secure Members Only area of the IFPUG website where you will find an active online bulletin board where members exchange tips and techniques related to software measurement you can even pose questions for the IFPUG community at large to answer.

Several versions of the manual are available, each describing the standard or variation e. Function Point Counting Practices Manual 4. The most important consideration when using any measurement to compare or evaluate different types of projects or contracts is consistency.

Again, this depends on your goals for measurement.

This practical guide covers the entire microservices landscape, including the principles, technologies, and methodologies of this unique, modular style of system building. While this website and much of the information provided are available free of charge to members and non-members alike, becoming cp, member of IFPUG has the following benefits:. It can also help improve forecasts of cost and schedule for new development projects and enhancement projects.
