Use a package called concurrently.

npm i concurrently --save-dev

Then setup your npm run dev task as so:

"dev": "concurrently --kill-others \"npm run start-watch\" \"npm run wp-server\""

Ultem

Ultem is a family of PEI products manufactured by SABIC as a result of acquiring the General Electric Plastics Division in 2007, developed by Joseph G. Wirth in the early 1980s. Ultem resins are used in medical and chemical instrumentation due to their heat resistance, solvent resistance and flame resistance. Ultem 1000 (standard, unfilled polyetherimide) has a high dielectric strength, inherent flame resistance, and extremely low smoke generation. Ultem has high mechanical properties and performs in continuous use to 340 °F (170 °C) and is easily machined and fabricated with excellent strength and rigidity.[4] Ultem 1000 has typical thermal conductivity of 0.22 W/m·K (but some sources give 0.122 W/m·K). It has "Questionable usage on alkaline solutions."[5]

agile BI

Create in MS word: 3-5 pages

describe how and Agile project methodology can be applied to business intelligence projects
provide 3 resons this could be a useful approach?
provide 2 challenges with this approach?
define a product backlog.

Agile method helps BI realize value fast, adapt to ever changing business requirement, and increases the customer satisfaction rate. Agile emphasize on interactive communication between customers, business analyst, developers, and other project members during all phases of project.

During project initialization phase, meeting with customers and understanding their requirement and expectation is essential for defining the project. Having a clear picture of deliverables will facilitate cost and profit analysis, risk and feasibility assessment.

Client information is also critical for setting up bidding strategies. For one-time customer, strategies tend to maximize short term gain, whereas for customer with future opportunities, strategies pivot to develop long term relationship. Companies can submit competitive bid to increase the chance of winning contract. Securing contracts will potentially change the course of the company and contribute to the companies’ future growth and success.

During project analysis and development phase, it is important to keep clients updated. Frequent meetings with client to inform them with project progress will keep business on track. If the milestones have been reached smoothly, clients can check and give feedback. If unexpected delay happens, explaining the adverse situation and cause to client will help work out a new schedule with client.

Client may also come up with new requirement as the projects runs. A new agreement may be reached on both sides. Designs can be revised to accommodate the new criteria. Lots of large projects can be broken down to smaller projects and is completed by finishing smaller projects in sequence. Agile is suitable for these type of projects.

Agile promotes shorter development cycles and faster delivery. Smaller project with scope scaled down is easier to manage, which accelerate processes of submitting temporary design, receiving feedback, and revision. Constant flow of information between development team and clients help all sides maintain on same pace. Therefore waste on unnecessary design and extra work is reduced and development efficiency is increased. Changes can be adapted in timely manner to better fit clients’ need.

At project deploy and operation phase, there might be minor system failure, bugs need to be fixed. Customer experience with the system may also show where the improvement could be made.

Agile will help business meet challenges from different industries. By updating and maintaining system regularly, and live testing the system on the market, systems have fewer flaws and become more user-friendly and competitive. Customers can also be trained to master system features, operations so that they better take advantage the system.

Implement agile mouthed can be challenging if clients have conflicted requirements for projects. When communication with different personal from clients, the objectives may vary and priorities deviate. This will confuse the development team, and may lead development in opposite directions.

Agile could also be challenging if development team is used to traditional systems. Switching from working with a well scheduled plan, design, and implementation process to an ever changing, customer oriented approach may be difficult to adapt.

Product backlog is an ordered list, with desired functionalities in product. It is usually short and can be completed in one development cycle.

memo to your organization

write a memo of intent in support of introducing a business intelligence initiative into your organization.

the memo should address:

how BI could augment the strategic objectives of the organization
what opportunities BI will provide
What challenges BI will face in being adopted (and how you plan to overcome them)
what methodologies will you use to manage the introduction of BI into the organization (project methodology, etc)
an other support or information you think would help your BI initiative become adopted.

You may use a real or fictitious company - please state assumptions as needed.

BI Benefits Agricultural Industry

People works in agricultural industry are looking for ways to make more profit. BI will empower them to reach this goal. BI helps enhance crop yield, increase agricultural efficiencies, and optimize produce market value. BI also helps lower financial cost, reduce natural and artificial risks, and decrease wastes.

BI takes advantage of historic data and modern technologies. Which creates relative accurate models of the crop yield from analysis on environment. Data from sensors in the farmland provide real time information of the crop growth, allowing farmers to activate equipment at precise agricultural stage. Predictive analysis based on real time market and historical price help farmers bring product on market when values are high.

BI gathers resources from government; private sectors… Which offer farmers funding and financing aid for purchasing and leasing, technology and equipment upgrade… Weather forecast and news alert farmers with adverse weather condition, update farmers with changing trade patterns. Farms can take precaution, plan ahead, and move away from risk.

BI facilities comprehensive planning, strategic decision making to minimize waste of time and money, and maximize agricultural process efficiency and return. BI creates opportunities for companies gaining competitiveness, expanding future growth possibilities.

Agile approach is good for implementing BI solutions. The objective is to speed up the data delivery to users, prioritize design to meet requirement, adding value to business with strategies.

The biggest challenge for BI is data acquisition. Accurate, real time, and historic data is required for analysis. Technology plays a key role in tackling this problem. Sensors in the field transmit real time data to control centers. Remote sensing techniques such as drone survey, satellite photo send images to geographic information system, historic stats are open on internet to view.
