What is the difference between "organizational development" and "organizational design"?

Thank you Mohamed, this is a great question.

To be able to develop (progress) as an organization a road map (organizational design)is required. This road map describes how each individual and department should behave and be equipped so that  everybody involved can contribute best to the achievement of the organizations desired development stages.

Organisation development deals with the people, and their development, knowledge sharing, etc... you can say it's handling the soft part of organisation, while org design is mainly concerned with structure and systems, and altering the more solid parts of the organisation

HR for HR: "Be aware of an organizational culture before deploying any HR practice/s as corporate culture is influancing the way of doing HR ANYWHERE," 

Cultural dilemmas: "Achieved Vs Ascribed cultures": Individuals in achieved cultures are judged on accomplishments while individuals in ascribed cultures are judged based on social factors, wealth, connections, family or gender. 

Orgnization Design is Key element for every firm to success in acheiving its goals, the orgnization's development is important stage or process to improve human resources through leadership for example ... Org, Design is Task oriented process Org, Development people oriented process
