Stellar nucleosynthesis is the corner-stone of many astrophysical problems. Its understanding leads to insights into the stellar structure and evolution and provides crucial clues to the physics of galaxies and of the Universe. Precise answers can be given to the questions `When, where and how are the chemical elements synthesized in stars?' However, in spite of the observational confirmation of many predictions, important weaknesses remain in many crucial details of the global view. We discuss here some of the theoretical developments which are required in order to improve the nucleosynthesis predictions for low and intermediate mass stars. We conclude on the necessity to get new observational constraints from detailed abundance analysis of post-AGB stars and of planetary nebulae.
