Studies have developed to describe the use of crowdsourcing techniques in the field of public health.    Collective intelligence results from crowdsourcing are generated in three broad categories of public care; Health Promotion Health research and health conservation.  Crowdsourcing also allows researchers to move from small homogeneous groups of participants to large heterogeneous groups beyond convenience samples such as students or more educated people. The SESH group focuses on crowdsourcing for health improvement. The tasks of participatory workers should be clearly defined. Staff should be provided with a detailed description of all the timing and content criteria that must be met in order to participate in and complete a crowdsourcing project. The project description is the basis for the acceptance of completed transactions and the next payment. As intermediaries, crowdsourcing companies must take into account the time requirements of their customers, but also plan with realistic assessments and give participatory workers enough time to carry out their tasks. In the event that tasks are offered directly through the customer and not through the crowdsourcing provider, the provider advises on clear task definitions and the appropriate schedule. As a general rule, there are no written contracts, confidentiality agreements or staff agreements with participatory workers.
For Amazon Mechanical Turk users, this means that applicants decide whether users` work is acceptable and reserves the right to withhold payment if it does not meet their standards.  Critics say that crowdsourcing arrangements exploit individuals in the crowd, and it has been asked to organize for their labor rights.    Crowdsolving is a collaborative but holistic method of solving a problem with many people, communities, groups or resources. It is a kind of crowdsourcing focusing on complex and intellectually demanding problems that require considerable effort, and the quality/singularity of the contribution.  One of the problems with crowdsourcing products is the lack of interaction between the mass and the customer. As a general rule, little information is known about the desired end product, and interactions with the end customer are often very limited. This can reduce product quality because customer interaction is an important part of the design process.  Companies have a number of motivations to use crowdsourcing to accomplish their tasks, to find solutions to problems or to gather information. These include the ability to offload peak demand, access cheap labour and information, achieve better results, access a wider range of talent than an organization could exist, and solve problems that would have been too difficult internally.  Crowdsourcing allows companies to submit problems on which contributors can work on topics such as science, manufacturing, biotechnology and medicine, with monetary rewards for successful solutions. While complex crowdsourcing tasks can be difficult, simple tasks can be done at crowdsourcing at a lower cost and efficiently.
 Open innovation platforms are a very effective way to crowdsourcingen people`s ideas and ideas for research and development. InnoCentive is a crowdsourcing platform for research and business development, on which difficult scientific problems are posted by many Solvern to find the answer and win a cash prize that can range from $10,000 to $100,000 per challenge.  InnoCentive of Waltham, Massachusetts and London, England provides access to millions of scientific and technical experts from around the world.
