What's the difference

I always strive for quality result. However I am also aware that time plays
very important role in software projects, therefore I always do my best to
keep the balance of these two. The bottom line is, I strive to deliver quality
products on time.

My definition in quality in software project is:

- Source code is easy to read/understand
- Easy to maintain
- Modular and systematic
- Future enhancement is easy to add
