Sammanfattning
The Defence and Security Company (DSC), has a variety of extremely complex products
with high requirements. Even though the DSC has a production, the complexity
of the products demands that some components are bought from suppliers. Some
components can be bought from suppliers "off the shelf" without further modifications
but many components are developed by the company or needs modifications to
satisfy the need. To make sure that the company communicates the right needs to an
external supplier, a product specification is created for each component developed
by the DSC or in need of modification. The product specification should include
drawings and requirement specifications detailed enough for the supplier to manufacture
the wanted component. Due to the time frame for the developing project
not always following the time frame for the delivery of components, the product
specification is not always completed when the external supplier is contacted. This
does not just make it hard for the supplier to create a good enough product, but the
very choice of which supplier to choose is affected. Also, the documented process
is not always followed and risk analyses are not always conducted. This leads to
problems as the project goes and in the end, the manufactured product might not
fulfill the requirements set by the company or the requirements are not extensive
enough.
The theoretical contribution is based on lean management, root cause analysis with
the 5-whys, project models, product specification, cultural influences within an organization
and Failure Mode and Effects Analysis (FMEA). The study was executed
by conducting exploratory, semi-structured interviews with stakeholders of the process
and by investigating documentations and regulations.
The proposed solution to this is to conduct a risk analysis early in the development
process to identify the risks and the complexity of the component. The risk
analysis is then used to rank the component as high risk or low risk. Depending
on the ranking of the component, it can be decided on how extensive the product
specification needs to be and where there is a need for control points in the process.
