Below are the steps I take to deliver final results to clients
Brief - I usually have the client or stakeholder inform and provide me all the available assets for my use in designing their ask. I will usually ask questions regarding every aspect of their design as well as for examples or inspiration they may have regarding their idea.
Execution - Once given all the needed information and resources, I will open up a design software that is best suited for the job and start working on the project.
Feedback process occurs afterwards and I iterate on the design until it is ready and beyond the expectations of the stakeholder.
Delivery - Once all feedback is given and I am done designing the project (in this case it is social media banners) I double-check for any typography/alignment errors and send all final deliverables to the stakeholder.
