进展 (jìn zhǎn) means 'to make progress, to advance' and is used for projects, work, or research moving forward. It focuses on the process or pace of development, unlike 进步 (jìn bù) which emphasizes improvement in quality or skill, and 前进 (qián jìn) which is more about moving forward physically or in a direction. 进展 is often used with adverbs like 顺利 or 缓慢 to describe how things are going.
