Opportunities

The goal of this proposal is to create an effective and efficient organizational business plan that will facilitate the future growth, profits and increase current customer base. Through analysis and investigation opportunities will be created that could address staffing, culture, resources, policies and procedures. In addition, the actions performed under this proposal will provide important information regarding network and information security and the ability to successfully protect customer information. The success of this proposal depends on several critical factors including effective communication, a clear understanding of the requirements, and most importantly Stakeholder and management support.

Business Architecture Requirements

As defined in the scope of this document, the purpose of this proposal is to provide analysis of the current business architecture and operations infrastructure in order to provide recommendations for recognized inefficiencies. The recommendations will provide insight to streamlining current processes and bridge the implementation of the new Smart Thermostat product line. The requirements for the business architecture, as directed by the Stakeholders, is to analyze current organization operations and infrastructure and propose a new business architecture design that will support new Smart Thermostat hardware and registration system. The final approved design will ensure the following:

1. System requirements for installation and communication of Smart Thermostat at installation sites to include:

a. Network requirements – DSL, Wireless

b. Mobile device requirements – Software version, Data requirements

2. User registration – User registration form requirements which include required fields such as:

a. First and last name

b. Installation address

c. Billing address

d. Email address

e. Phone number

3. Device registration – The Smart Thermostat will register to the system and provide the following information:

a. Serial number

b. Model number

c. Firmware version

d. Device name (Host name)

4. Data Collection – The Smart Thermostat will record and send data to the data center for monitoring and billing purposes. The data will include:

a. Current Environmental status (temperature, humidity)

b. Energy usage

c. Location

d. Current Energy Schedule

e. Filter lifecycle

f. Power status

5. Privacy – The design will include procedures to safeguard customer, device and system data to ensure confidentiality and integrity.

Business Architecture Design

The purpose of this proposal will introduce processes that will streamline operations to efficient support the new Smart Thermostat system. Monitoring, registration and connectivity are paramount in allowing customers to setup their new Smart Thermostat devices. The customer must register the device, setup account information, setup mobile features and accept the privacy policy.

Registration System

The registration system will establish customer Smart Thermostat account. The system will allow multiple devices to be registered to a single customer account. The System Identification Number and the units MAC address will be used to associate the device with the customer account. The data collected for the system will include the following:

· First and last name

· Mailing address

· Email address

· Phone number

· System ID (Device Serial Number is hard coded.)

· Model Number

· MAC address

· IP address

· Firmware version

· Location

As shown in Figure 1, the system allows one user to register multiple devices with each registered device having exactly one location.

The registration process (as shown in Figure 2) involves that transfer of sensitive personal customer information, which is considered confidential. Customers of Smart Homes Inc., expect that all personal information be kept private, in accordance with the organizations privacy policy, and should this information be compromised could lead to civil litigation. For this reason it is imperative to maintain a high standard in regards to network and data security. At minimum these standards should include:

· 128 bit minimum encryption methods to safeguard personal confidential data.

· Cryptographic protocols such as HTTPS, SSL and IPSec for secure data transfers over Internet.

· Strict compliance auditing practices.

· Comprehensive disclosure agreement in accordance with State and Federal regulations.

· Proper authentication methods for validating device information to the system.

Figure 2 – Customer Registration Process 1

Monitored Data System

The Smart Thermostat device will record, store and transmit recorded information to the Smart Home Inc. data center once every 30 minutes from the time the initial setup configuration is saved. User and device registration information will be uploaded every 12 hours for authentication purposes. The Smart Thermostat will adhere to the privacy policy when collecting and uploading data. To ensure product satisfaction and enhance development all device errors will be recorded and uploaded. This will provide the necessary information when developing system and firmware updates. As shown in Figure 4, if a Smart Thermostat does not register with monitoring system within a 48 period, then service will be immediately suspended. The customer will be required to contact the Smart Homes. Inc., Help Desk to resume service.

Figure 4 – 48 Hour Data Collection Rule 1

Remote Connection System

The Stakeholders have made it a requirement that customers have the option to remotely manage the Smart Thermostat from a mobile device. This innovative feature is a top selling point for the product line and will be highly marketed. In order to ensure a superior customer experience this process must undergo a thorough analysis. The system will be outline to provide a visual depiction of each step in the process for better understanding. Figure 5 shows a conceptual process model from the initiation of the remote connect process to the subsequent connection closed point from an internal prospective.

Internal View of the Organization

Internal View of the Organization

During the investigative process of the development of the business architecture inefficiencies were discovered. Part of the goal of this process is to ensure that the organizations are utilized in the most effective manner. As part of the approach in developing this proposal, the organizational structure of the company was obtained (Figure 5) and analyzed.

Figure 6 – Smart Homes Inc., Org Chart 1

As shown, the CEO is atop the organization with all other business functions displayed at the second layer with the IT function falling under the COO. To gain further perspective, survey questions were developed and follow-on survey was conducted across the organization. A Likert scale was used to ask the following questions:

Results from a survey conducted by our company regarding various aspects of the Information Technology Department an its business practices where analyzed. The questions were based on a Likert Scale (Likert scale) and consisted of the following questons:

1. Do Senior management support IT?

2. Are business goals and vision defined and shared?

3. Does good communication exists between IT and all non-IT departments?

4. Is IT is involved with strategy development?

5. Is IT initiatives tied to business goals?

6. Do you believe that IT understands the business?

7. Are IT projects are driven by business needs?

Survey question were sent out to 200 respondents with a 90% response rate with over 52% of the respondents disagreeing or strongly disagreeing with the questions.

The survey reveals inefficiencies with the current business practices, which directly affect the success of Smart Homes, Inc. and the smart thermostat product line. The current organization promotes these issues and allows for IT needs in non-IT departments to circumvent the CIO effectively missing the opportunity to align the business. In order to build a solid foundation for establishing solid communications within IT and non-IT departments significant restructuring is needed.

In an effort to align IT with the business, improve communication, and provide adequate resources to meet the smart thermostat proposed architecture (Figure 4), Smart Homes, Inc. will benefit from the organizational structure proposed in Figure 6.

Figure 6 – Proposed Org Chart 1

The organization structure elevates the CFO, CIO and Legal functions under the CEO and places the remaining functions in a third and fourth tier. This change will allow for legal oversight of various functions of

Human Resources

and allow all IT communications and needs to filter through the CIO. A newly formed Operation Department will house the IT and operations divisions all of which play critical roles in the new thermostat product line.

A communications link between two points:
Established a connection to the Internet.

Customer

One that buys goods or services.

Data

Distinct pieces of digital information. Data is usually formatted in a specific way and can exist in a variety of forms, such as numbers, text, etc. When used in the context of transmission media, data refers to information in binary digital format.

Device

A device is a unit of physical hardware or equipment that provides one or more computing functions within a computer system. It can provide input to the computer, accept output or both. A device can be any electronic element with some computing ability that supports the installation of firmware or third-party software.

DSL

Digital Subscriber Line or Digital Subscriber Loop. Refers to the variety of different types of Digital Subscriber Line protocols – high-speed data transmission protocols that are compatible with regular copper telephone wire. DSL is typically used to provide a continuous, high-speed connection directly to an Internet Service Provider

Email

Electronic mail. A service that sends messages on computers via local or global networks.

Home network

A local area network (LAN) that connects the PCs in a home and lets users access the Internet simultaneously, share drives, share files and printers, and play head-to-head multi-player games.

Internet

A network of networks; a group of networks interconnected via routers. The Internet (with a capital I) is the world’s largest internet.

Internet Access

Access to the Internet via a dial-up account via telephone circuit or direct connection.

Internet Protocol

(IP). The IP part of TCP/IP; the protocol used to route a data packet from its source to its destination over the Internet.

IP Address

The unique 32 bit number assigned to each computer connected to the Internet and used by the TCP/IP protocol to route packets of data to their destinations. The number is usually written in shorthand “dotted octet” notation in which the 32 bit address is grouped into four sets of 8 bits. Each of those eight-bit sets is converted into a decimal number, and the four resulting decimal numbers are written separated by dots. Most Internet addresses consist of a network portion and a node portion. The address for a host must be unique on the network. When you connect to a web server, for example, you may tell your browser to connect to www.mysite.com, but your computer ultimately has to translate the name to its IP address, 109.208.000.1, before the connection can be made
