Customer Relationship Management (CRM)

connects ERP system to those of its customers, manages marketing sales and customer services

Supply Chain Management (SCM)

connects companies that supply's for products

systems development life cycle (sdlc)

waterfall, interative, agile

hardware diagram

business analyst strategy

used to work as a liaison among stakeholders in order to understand the structure, policies, and operations of an organization

project testing framework "v" model

validation: business need -----> system testing requirements -----> user acceptance test verification: design -----> integration and regression test construction -----> unit test

reasons data fails

- data migration: - data quality: data not maintained - lack of business analytics and intelligence

cutover

"opening" the new IT system for business processing, to go live

longterm challenges with failure

- organization (employee changes) - data (formatting errors)

reasons processes fails

- poor requirements - business cycle often faster than IT implementation - automation of poorly designed process

reasons hardware fails

- poor response time - poor testing

Reasons organization fails

- silo effect: you need to change how you think before you change how they think - culture and values, beliefs, practices - fear, uncertainty, doubt

reasons software fails

- software capabilities not meeting process (no effectiveness) - software defects/bugs (no accuracy) - inadequate documentation & training - poor testing

John Kotter's 8 Steps to Leading Change

- thaw 1) set the stage: create urgency 2) pull together guiding team 3) develop the change: how will the future be different - reshape 4) communicate for understanding 5) empower others to act - freeze 6) produce short term wins 7) don't let up 8) create a new culutre

1. define and manage service levels 2. educate and train users 3. advise and assist users 4. manage problems 5. manage the configuration (change management) 6. identify & allocate costs

IT discovery portfolio

1. identify opportunities 2. manage and mature ideas 3. assess concept feasibility & risk 4. develop solution value proposition

IT project portfolio phases

1. planning 2. requirements 3. design 4. construction 5. testing 6. deployment

services oriented architecture (SOA)

1. web service 2. composite applications

process change strategies

Business process automation (run), business process improvement (grow), business process reengineering (transform)

Servers

Computers that exist only to provide things to others.

Local Area Network (LAN)

Connects a group of computers in close proximity, such as in an office building, school, or home

erp system

Demand to Supply (plan) supplier --> requisition to pay (buy) --> plan to produce (make) --> inquiry to sell (sell) --> customer Financial Accounting (track)

pilot (phased) implementation deployment

Deploy the new IT system for only a small group of people, typically a business segment

risk heat map

Frequency/severity Low/low - retain loss High/low- loss control Low/high - insurance High/high - avoid

Wide Area Network (WAN)

Spans a large geographic area such as a state, province, or country

single (big bang) cutover deployment

Stop the legacy IT system and cutover the new IT system in one-step

SIPOC

parallel processing deployment

Utilize the legacy IT system in parallel with the new target IT system

project

a temporary endeavor undertaken to create a unique product, service, or result

norm

able and unwilling

perform

able and willing

IT assets portfolio phases (legacy)

accept assets --> supports assets (BA) --> evaluate assets --> disposition assets [ased]

Product Lifecycle Management (PLM)

administers research, design, product management

evaluate assets

assets the business value and fit of IT assets

four key skills of a business analyst in processing

business acumen, problem solving, process management, total work systems

buying software

characteristics: commercial off-the-shelf (COTS), change process to meet software pros: leverage best practices, develop configuration skills cons: possible legacy integration challenges, newly trained staff may leave. provider upgraders require regression testing

building software

characteristics: in-house, custom, can change software to meet process pros: satisfies unique requirements, develops coding skills cons: slow delivery, lower quality, company must maintain

enterprise IT (EIT)

cross-functional business processes

As-is system

current system, legacy

erp & inter-enterprise system

customer relationship management (CRM), product lifecycle management (PLM), supply chain management (SCM), supplier relationship management (SRM)

information

data in relationship

master data

defines entities used in execution

work breakdown structure:

defines the hierarchy of project tasks, subtasks, and work packages

factor rating method

determine criteria, assign weights to each criteria, weight X rating = score

disposition of assets

determine next steps for IT assets

function IT (FIT)

discrete task

transactional data

documents the outcome of executing business processes

network IT (NIT)

enables interactions without parameters

Supplier Relationship Management (SRM)

enables the quotation and contracts processes; an extension to the procurement and planning of ERP's

IT Portfolio Management

includes: IT asset portfolio, IT discovery portfolio, IT project portfolio

inter-enterprise processes

erp in the middle, plm (top), crm (right), scm (bottom), srm(left)

situational leaders

form, strom, norm, perform

business process automation (bpa) = run

goal: keep the lights on, limited changes, focus is on as-is system

network admin

hardware

evaluating risk

high risk low business value: disregard, high risk high business value: consider, low risk low business value: consider, low risk high business value: execute

evaluating technical fit

high tech fit low business value: reposition to maintain, low tech fit low business value: replace, low tech fit high business value: reengineer to maintain, high tech fit high business value: MAINTAIN.

what purpose does a business analyst serve

in between business needs and IT capability

inter-enterprise IT

information systems that are shared by two or more independent organizations

database admin

infrastructure

steps of transformation of people

invest --> understanding --> accountability --> ownership

networks

local area network (LAN), wide area network (WAN)

phase

major milestone or review point (gate)

accepting assets

manage the intake of the new IT assets from IT project portfolio

tasks

measurable units of work

business process improvement (bpi) = grow

more of the same, moderate changes, focus on as-is and to-be

data migration
