The Framework of Analysis provided the steps for the decision-making process distinguishing an Inception phase, a Situational Analysis phase and a Strategy Building phase. Data, information and knowledge were gathered, analyzed, processed and aggregated to inform and interact with stakeholders throughout the phases. The decision framework was built up from a high-level vision (“A safe and sustainable Manila Bay”) to 5 management objectives specified by 10 assessment indicators. Future developments on population development, economic growth and climate change were combined with measurement packages for improvements in waste management, water quality, ecosystem protection, flooding and inclusiveness. The assessment of measurement packages provided input to the formulation of an action planning and investment program.
