What does PDDM mean in MANUFACTURING

A Preliminary Design Decision Memo (PDDM) is an official document composed of preliminary design decisions made by a project team. It outlines changes the team proposes to make to a project's overall architecture and implementation, along with key considerations and trade-offs associated with those decisions. The PDDM also serves as an agreement for proceeding with the proposed changes in accordance with the outlined criteria.

Your team should create a PDDM if it needs to record and communicate design decisions that affect the overall structure or architecture of your project. The PDDM ensures that all stakeholders clearly understand the implications of the proposed changes, so that informed agreements can be reached quickly and accurately.

Typically, teams compose their PDDMs collaboratively with input from the primary stakeholders, including designers, engineers, product managers, legal teams, executives, etc. This ensures that everyone’s perspectives are taken into account when making key design decisions.

Depending on the complexity of your project and the scope of proposed changes, it may take anywhere from one day to two weeks to complete a PDDM. At minimum, your team should plan on spending at least one full day on its creation.

At minimum you should include information about the specifics of your proposed changes (e.g., what code modules you intend to modify or refactor), key considerations for each change (e.g., resource costs), agreed-upon solutions or alternatives (e.g., rollback points or contingencies), arguments for why these choices make sense given any constraints (e.g., time budgets or technical restrictions), signoffs from necessary personnel or external parties; e.g., legal teams).

Generally speaking, it’s best practice to start by introducing the context of your decision as well as any existing conditions or parameters that will shape how it's implemented; then provide background and details regarding both your current design and proposed plans related to implementation; next come your core considerations for making this decision; finally present any additional data that might prove useful in determining whether meaningful progress can occur when following through on your plans.

Absolutely! Without properly documenting details like those mentioned above – concerning resources required or constraints – individuals could find themselves facing significant unanticipated obstacles when moving forward with development efforts which could easily compromise deadlines and result in higher costs than expected.

You will then need to review it with all relevant personnel who need agreeing upon certain aspects before approving them – such as product managers who need signoff from senior leadership – in order to have confidence in proceeding further.
