First thing first, Need to revise what ever changes that could be made and it's impact on the current work, - give a exact impact study according to. - Time - Cost - Other consultants feed back impact on time and cost. Try to find middle ground for design intent. Landscape design is about making a place and a good design should deliver this message from the first day of work. Keeping in mind that sharing work progress and workshop with client is a great way to avoid such situations.

As a former client and now on the consultant side, my advice would be to focus on the long-term relationship - not just the project in hand. In this way you become a trusted advisor and better able to negotiate an amicable way forward. In short, be flexible within reason…Live to see another opportunity.

It's not always great idea to find a middle ground . In my opinion we should be flexible and organized simultaneously. If they sleep and dreamed a new idea that will change every steps , it could be nice to lead them toward the contract.

Communicate with all parties - the owner, the designer, all departments - to study the extent to which the change affects the cost, time periods, and other factors. After completing the approvals, a change order is issued by the owner to all parties to work based on the above.

Understanding the project's lifecycle approach being applied is the key. While the waterfall approach is strict with changes, the agile approach embraces them. If the project follows the waterfall model, any change—including design adjustments—requires submitting a formal change request. The PM then analyzes the impact on the initial project management plan (cost, timeline, ...) and communicates the results to all stakeholders, to help them in their decision-making before approval. On the other hand, if the project follows an agile approach, changes are welcomed. Once the current iteration is completed, the PM informs the Product Owner to update the backlog list so the changes can be reprioritized by the design team for the next iteration.

Los cambios que se realicen deberán analizarse para ver si son factibles, y como afectarán al resultado. Además, implicará una modificación en el presupuesto inicial, de la que deberán ser conscientes las partes interesadas. Todo es posible siempre que encaje dentro del proyecto y se asuman las consecuencias. Otro aspecto a tener en cuenta es la compra realizada de material, si se puede devolver o tiene que asumir el coste el cliente. Todo de puede anañizar y llevar a cabo siempre que seamos conscientes de que los cambios no solo afectarán al diseño, si no a todo el proceso en cadena.

Navigating stakeholder demands for late design changes requires a strategic blend of flexibility and communication. First, assess the impact of the changes on project scope, timeline, and budget. Engage in transparent discussions with stakeholders to align on priorities and manage expectations. Implement a structured change control process to evaluate and integrate modifications without compromising project goals. Balancing adaptability with rigorous management practices will ensure that you address stakeholder needs effectively while maintaining project integrity.

It depends on the extent of the change and how it will impact the project and others on the project. Changes can add value to a project such as cost savings and enhance the project value.
