Injection molding is a complex and dynamic process that involves many variables and uncertainties. Changes in the construction flow process, customer demand, and supplier restrictions can have significant impacts on the project’s cost, quality, and delivery. Therefore, it is essential to have effective project management skills and tools to handle these changes and ensure the project’s success.
Some of the common challenges of managing changes in injection molding projects are:
Scope creep: This occurs when the customer requests additional features or modifications that were not originally agreed upon or planned for. Scope creep can increase the project’s complexity, duration, and budget, as well as affect the product’s functionality and performance.
Design changes: This occurs when the product design is altered or revised during the project’s development. Design changes can be caused by customer feedback, testing results, regulatory requirements, or technical issues. Design changes can affect the mold design, material selection, processing parameters, and quality standards.
Process changes: This occurs when the manufacturing process is modified or adjusted during the project’s execution. Process changes can be caused by equipment breakdowns, material shortages, quality problems, or environmental factors. Process changes can affect the production rate, cycle time, scrap rate, and product consistency.
Supplier changes: This occurs when the supplier of a critical component or material is changed or unavailable during the project’s implementation. Supplier changes can be caused by market fluctuations, delivery delays, quality issues, or contractual disputes. Supplier changes can affect the product’s availability, compatibility, reliability, and cost.
Some of the standard tools and methods for managing changes in injection molding projects are:
Change management plan: This is a document that defines how changes will be identified, evaluated, approved, implemented, and monitored throughout the project’s lifecycle. A change management plan should include the roles and responsibilities of the project team members, the change request process and forms, the change approval criteria and authority, the change implementation procedures and tools, and the change control board.
Change log: This is a record that tracks all the changes that occur during the project’s execution. A change log should include the change number, date, description, reason, impact, status, and owner. A change log helps to document the project’s history, communicate the project’s progress, and analyze the project’s performance.
Change impact analysis: This is a technique that assesses the effects of a proposed change on the project’s scope, schedule, cost, quality, risk, and stakeholder satisfaction. A change impact analysis should include the identification of the affected project elements, the estimation of the required resources and time, the evaluation of the potential benefits and drawbacks, and the recommendation of the best course of action.
Change request form: This is a tool that formalizes a request for a change in the project’s scope, design, process, or supplier. A change request form should include the change description, justification, priority, impact assessment, alternatives analysis, approval status, and implementation plan. A change request form helps to document the change request details, facilitate the change approval process, and monitor the change implementation progress.
