A project is a temporary endeavor undertaken to achieve unique product or services. We can say the project is success if we are able keep the customer requirements satisfied or exceeding , complete the project with in the scheduled duration, complete with in the given budget & mostly the acceptance agreement from customer. Always to have a project running there should be a proper business justification for the same.
Project Business Case:
The project business case lists the objectives and the reason for the project initiation.It helps to measure the success of the project at the time of project closure with the project objectives. Business case is a document that is used through out the project life cycle and it gives the go or no-go signal for the project. The business case should have business needs, analysis of the situation, recommendations for the problem.
The environment in which projects operate may have influence on them. These can be positive ( In favor) or negative (unfavorable) impact on the project. The two major influencing factors are Enterprise Environmental Factors (EEFs) and Organizational Process Assets (OPAs)
Enterprise environmental factors arise from environment outside of the projects and often outside of the organization where as Organizational process assets are internal to the organization.
EEFs and OPAs
Enterprise Environmental Factors:
Enterprise environmental factors are the influencing factors that influence, constraints the projects which are not under the control of the project team.These can be internal or external to the organization, and these factors can have positive or negative impact on the project deliverables.
Some of Internal EEFs are
Organizational culture and governance : Vission , Mission, leadership styles, code of conducts etc.
Geography distribution : Work location, Virtual teams etc.
Infrastructure : Communication channels, equipment's, hardware etc.
Resource availability: Contracting, Subcontractors etc.
Softwares: Scheduling softwares, Automated tools, Configuration management etc.
External EEfs are
Market conditions : Competitors, Brand, trademarks etc.
Social and cultural influence: Political climate, ethics etc.
Legal restrictions : Country , local laws, data protection laws etc.
Government standards: Government agency regulations on environment, products, resources etc.
Industry standards: Industry standards on quality, productions, products etc.
Financial regulations: Currency exchange rates, interest rates, inflation etc.
Organizational Process Assets:
The processes, policies, procedures, knowledge bases and plans available in your organization become the Organizational process assets. These are used by project teams for their reference and as guidelines to run their projects and these influences the management of the project.
The lessons learned from previous projects, historical information etc are stored in OPAs. OPAs include the artifacts, practice and knowledge from all previous projects performing in the organization. OPAs are internal to organization , project team is able to add or update OPAs as necessary through out the project lifecycle.
EEFs and OPAs are input for lot of Project management processes. Outside of enterprise environmental factors and organization process assets other factors like power, influence, political capabilities of people in the organizational system can also impact the projects.

This means the data flow & collected by the resources are going to increase exponentially. Data is the key for the business & or we call it as the business itself. It all depends upon how the enterprise is using the data.
Artificial Intelligence the Key to Unlock IoT Potential:
The era of normal connected IoT devices are going to change, we are seeing the involvement of AI & Machine learning with IoT now. This is going to change the entire world how it is running now & this is going to be a key factor in future. We are talking about autonomous driving cars, Speech recognition & Computer Vision. Think about a world as we see in movies where robots are talking to each other, Cars are driving automatically, Fridge is talking to Television, You can enter to an virtual reality to do all your needs. Its sounds exiting as an adventure , at the same time we are seeing a great risk & catastrophic if something goes wrong.Just like i Robot :).
Adoption of best IoT security Practices:
This will be the key turning point or deciding factor on how our world is going to run in future. There should be defined standards for all IoT enabled products & have to undergo strict security testing which will ensure that data is safe & at the same time we don’t end up like a Judgement day in Terminator. Cyber attacks is increasing , the major concerns from consumer is regarding security of IoT devices. We have to look from bother software & physical side of security. At the same time the device can be hacked through software, all the devices are vulnerable physically also. We are expecting the industry to respond , considering this as the priority and deploy the latest security technologies and adopt security best practices. We can see already few of the government security agencies & organization are collaboratively working on these.
Blockchain IoT :
IoT and Blockchain are the two world changing technologies trending in this era and in the beginning of their adoption curve. We are looking forward to see enormous futuristic opportunities when these two technologies merge together.
what is blockchain : Blockchain is an encrypted, distributed computer filing system , it is a growing list of records, called blocks, which are linked using cryptography. Block chain certainly is real however may not be completely ready in 2018 for adoption in every industry. Blockchain is going to be technology that will make a real impact across industry sectors along with IoT. Blockchain is the invention from brain of a single person or a group of person know by pseudonym, Satoshi Nakamoto. Digital currency , Bitcoin is first majority used purpose however now industry is finding the potential use of it as technology.
