The term "coalition" is the denotation for a group formed when two or more persons, faction, states, political parties, militaries etc. agree to work together temporarily in a partnership to achieve a common goal. The word coalition connotes a coming together to achieve a goal.

there are five steps of coalition-building:

Developing a party strategy: The first step in coalition-building involves developing a party strategy that will lay the ground for successful negotiation. The more effort parties place on this step, the more likely they are to identify strategic partners, negotiate a good deal and avoid some of the common pitfalls associated with coalition-building.

Negotiating a coalition: Based on the strategy that each party has prepared, in Step 2 the parties come together to negotiate and hopefully reach agreement on the terms for the coalition. Depending on the context and objectives of the coalition, these negotiations may be completely secret or partially public. While some issues may be agreed on with relative ease, others may be more contentious and require different approaches to reach compromise.

Getting started: As negotiation begins to wrap-up, the agreement between political parties needs to be formally sealed. This includes finalizing a written agreement, securing formal approval of the deal from the relevant structures of the coalition’s member parties and announcing the coalition details to the general public.

Working in a coalition: As the coalition partners begin working to implement their agreement, they will need to maintain good relations by continuing efforts to increase or sustain trust and communication among the member parties. Each party will also need to strike a balance between respecting its obligations to the coalition and maintaining its individual identity.

Drawing lessons learned: Regardless of whether it plans to move forward alone or in another coalition, it is important for each party to review and document lessons learned
