Tuckman's team development model depicts from where a team is formed to the various stages they might experience before the end where the objective is achieved and these includes.
1) Forming: here they are just being put together
2) Storming: conflict and competition begin to arise
3) Norming: here agreement and consensus is reached as roles and responsibility is clear.
4) Perform: They start carrying out the roles and responsibility
5) Adjourning: Task is complete and they are discharged

Contract performance review and continuous improvement is the stage 11 of the CIPS procurement and supply cycle.
In order to effectively manage supplier performance and contractual obligations, the suppliers per-formance against key performance indicators (KPI) should be reviewed regularly. This KPI should have been agreed doing the post contract award negotiation. In addition to review KPIs suppliers and the procurement team should work towards continuous improvement. This is a continuous ef-fort to improve product or services within an organization. This may involve improving quality, reducing waste in the supply chain and focusing on innovation. It is an ongoing process that works toward perfection.

When a fixed asset reaches the end of its life, it requires decommissioning before reconditioning or disposal.
Decommissioning is to observe all the safety measures and technical procedures and stop active machinery or an asset from operation (example; gas plant, power generator, transformer etc.
Decommissioning process include the following aspect
1) Preparation: Plan the process
2) Dismantle: Take the asset apart and remove hazardous waste
3) Processing: make safe any hazardous waste
4) Disposal: Ensure paper work is received to confirm removal and disposal

Organizational culture is made up of behaviors, traits, values and beliefs and these differ signifi-cantly across the globe. Gestures that may be positive in one country can be highly offensive in another. This culture could mean; for example, individualistic/collectivistic, masculine/feminine, uncertainty avoidance, power distance, Time perspective, indulgence/restraint.
When negotiating and forming contracts within the extended supply chain, it is important that the culture of the suppliers is understood to be compatible with the buying organization or else their might be loss of reputation, time, money material and equipment.
Also, being not aware of what is an acceptable ethically behavior in global sourcing can cost a buying organization. In some countries, bribery and kickbacks are a standard part of doing business. If procurement professional is not aware of the fact that some countries methods of doing business involves or expect kickbacks, for example, this could be costly to the organization and cancel out any savings that had originally been seen.
Cost of poor quality and rework: if the product or service quality is poor the organization may not satisfy it customers and this can lead to a loss of reputation in the market. For example, a residential building construction company contracting a supplier that supply would require home owners to reinstall a new door within three months. The organization would spend more funds in carrying out rework.
More administrative cost in contract management: an organization will have to manage it sup-pliers and the contracts to ensure they are delivering what they were contracted to do. A poor con-tract management is a waste in the process of delivery that can lead to loss of money. Also, to cor-rect this would cost the organizations administrative cost.
